You can't convince a woman to do anything she doesn't want to do. You can test the water to see how she reacts to the suggestion, but if she's not interested, she's not interested and nothing you can do or say will change her mind, unless she changes it for herself.

Ask her if she's interested. If she says "no" then it's "no". If you talk her into doing something she doesn't really want to do she might just end up resenting the hell outta you.

With a gun!

I didn't have to convince Ann into anything. She initiated our first fmf threesome when she was about 40 years old. It was also her first bi experience. Our threesome relationship lasted almost three years. Ed

My girlfriend often talks about it during sex. It's still a fantasy for her so I talk it through and it makes her super horny.

I know from previous relationships that a no is a no.

I would go to a swingin club first. Let nature take its course,

Would that be with or without your partner?

Him: Hey babe, I'd love to try a threesome sometime.

Her: No way

Him: Howsabout a swingers club then?

Her:

Him: OUCH!!!

Here's how our conversation goes whenever I bring it up:

Me: Let's get Kinky and try a 3way.
Her: Do you not like my sexin'?
Me: I'm gonna go take out the garbage.

It will happen when it happens, don't push it

I should talk, I have been unable to convince my wife but I think you have to find a guy she really likes then plant the seed in her head that she would enjoy him with your blessing, only suggesting it when you are making love to her and she is very horny. Then keep aware of what you want her to do and listen to her carefully when she talks about him. It will take a lot of time if she is like my wife.

When I was in college I dated the same girl for over 2 years and the longer we dated the more comfortable we felt like talking about some touchy subjects. One of our ‘Pillow Talk Topics” involved the pro’s and cons of a 3some.
The first thing I’ve noticed is...if the GUY brings up the idea...the woman is immediately wondering “why?” ....assuming he’s either interested in some other woman or simply growing tired of his wife or GF. This is a dead end no matter what he says after that because the suspicion is there.
However, the best chance is to ask her “If you and I were not a couple...who among our friends or acquaintances would you be potentially interested in sexually?”
She may be reluctant to tell you the first time you ask..but if you keep at it playfully and having fun wth it....she’ll probably say...”Well..if you were not in my life I’d probably want to date Gary (or whoever).”
Then you plant the seed by saying maybe sometime for your birthday I’ll get Gary (or somebody) to join us for a 3some.”
NOW the thought in her mind isn’t that YOU want to bang one of her hot friends ...but rather you are open minded enough to want to arrange for her to have an exciting fantasy experience come to life for her.
Whether or not it actually happens is no guarantee, of course, but it gives her something to think about...and sometimes in life opportunities present themselves.
Once she has an MFM experience... it becomes more likely she will be open later to a FMF...fair is fair..

How do you get her to go to a swinging club?

My true story.
My wife was a sweet innocent church going Catholic girl when we mat at 17, (she honestly thought that every time a woman had sex she had a baby) and that her mother (A Catholic) must have been a very sexy woman as she had 6 kids, I had a tough job educating her I can tell you, "and the Catholic church has a lot to answer for".
I took her cherry when we were 18, we married at 21, had our family when we were 28 and 30, wife had her tubes tied after our second child so all sex since then has been bare back.
I met up with an old school mate and the wife and I started hanging out with them and their children around the same age as our children, over a few beers at a BBQ (my wife does not touch alcohol at all, "ever" the mate and his wife told us they belonged to a nudist club and invited us along for a visit, it surprised me when the wife agreed to go, and even more when she agreed to join, we even ended up with our own on site van there, it was soon clear that their was a lot of wife swapping going on there and naturally I was very interested in joining, but the wife said NO.
I kept hinting, she kept saying NO, but I over time I sensed she was weakening, it was funny / strange being at a party and seeing other couples going home with other partners knowing they were swapping for the night, then catching up with them the next day and them behaving as if nothing had happened, we were invited to nudist parties where we knew they were waiting for the wife and I to leave so they could swap partners once they found out my wife was not going to join in, we were even invited to a full on swinging party where we could see what was going on without being committed to swap ourselves, a very rear thing to happen, she came ever so close that night but chickened out at the last moment.
To be honest it was ever so frustrating, then one night we were at a nudist party, I was called away to work, we arranged for the wife to get a lift home with friend at the party so I could go straight to work, next day we were all going to the nudist club and I was going to meet the wife there.
The next morning I arrived at the club, went into our van and undressed, the wife walked in, kissed me good morning and said "I was a naughty girl last nigh with Joe" the guy who took her home, my reply was "a bit of a kiss and cuddle never hurt anyone" her reply was "it was more than a kiss and cuddle" I barred up straight away, eased her on the bed and started fucking her while she told me in detail what had happened, I swear her pussy never felt so hot as it did then.
Basically Joe's wife had to leave the party because of trouble with their baby sitter, Joe took the wife home as planned, the good night kiss turned into a full on fuck, when we walked out of the van all eyes were on us, the wife had told her girlfriend what had happened and everyone knew we were now swingers, the following Tuesday Joe and his wife visited us and we swapped wife's.
We were 35 and married 15 years at the time, that opened the door to 35 + years of swinging, swapping and M F M threesomes + 2 F M F threesomes, I prefer the M F M threesomes myself we are now mid 70's, married 56 years, our last threesome was 2 years ago with a 53 year old guy we met in a chat room, then the wife said enough was enough "I cannot really complain".
If you have taken the time to read all this my advice is never push the issue to the point where she has to say NO, plant the seed in her mind, let her think about it and that you are interested and take it from there, but once you push to the extent she says NO you are behind the 8 ball.
Good luck.

It's an old thread and the OP is too vague to be answerable.

If she has objections you have to know what they are or you don't have any chance at all to address them.

If she does indeed have objections they are most likely legitimate but that doesn't means that they can't be overcome to her satisfaction. It depends on what the specific objection is and her reason for having it.

Yes, if a guy brings it up she'll be suspicious. But no, that's not automatically an indication that it's a lost cause. Not at all.

with my wife, girl friend at that time I just brought up the subject, had done it with ex wife, she sounded interested because she had very limited exposure before getting with me. long story short we have had 3suns with 4 different guys since then, she luvs being center of attention and I luv seeing her sucking and fucking another guy. but don't push it or you will be sorry she has to be willing

We're together 53 years and with my prostate cancer (yanked it out) I don't hardly have the juices required to get it up anymore. I'd sure like to have The Bride enjoy a good one and I'll join in to help her and him along.

I've never been married, but having participated, let the girl or woman initiate it if that's what she wants.

Find a club that has guest nights! You can attend as a guest, observe & socialize & no pressure to undress or participate. If porn is part of your sex life, I'm fairly certain she'll like the live action! NO PRESSURE on her, let her take the lead. If nothing happens that night, no biggie, enjoy each other that night, then you can discuss over morning coffee where she might want to go with it... It's how we started, & where the Mrs. found out that thick cocks are in better in person!

Try watching some porn with threesomes and see how she reacts. You could she if she's getting excited .

Ask

I told my wife how my mate told me he’d like to join us for a MFM

She was so horny. Now she fantasises about being spitroasted every day she say and uses it to help her orgasm.

Hubby here:
How do you get your wife to NOT be involved in a threesome? Like, how do you prevent it? LOL. I don't have this issue. MMF or FFM. Or FFFM. I'm not a rock star but I have stayed in a Holiday Inn Express at some point...

I would love to have a mfm threesome with my wife but she flat out said no. So I leave it like that. Because I agree she has to want to do it just like she initiated the idea of taking and sharing nude pics. So I figure in time she may want to try it as we role play alot about her being with another man and i see how wet she gets so I wait patiently for that day to come and if it doesn't well I'm okay with that as well
