You described the art class and happenings very well. However, you should not have to be standing naked or undress in front of the class if the class has not started. The instructor has to be professional and allow you some respect. You can bring a robe to cover your body before the class begins, between poses, and during rest. The posing is rewarding and can have great impacts on frash or new students (because they have never seen or stared at a fully nude person for so long, drawing the part visible to them. As in a previous post, I have done the modeling myself and continue to do this in my older years. I enjoy it, make new friends and the nudity just fades away whe we discuss the drawings/sketches some artists have made. As a matter of fact, I am modeling this week on Tuesdat and on Thursday at two different studios. I'll get paid but I am not interested in the money, I just do this now to stay active. In my former youth, I would do erotic poses for some artists that were into that stuff and enjoyed the provocative poses and standing cock in some poses. In some sessions, I would pose with a female model and we would do great poses for the artists. Since you have now started posing, it will be good for your self esteem and take some comfort in your apperance, good or bad, scares, blemishes, crooked toes, or whatever. I hope you enjoy yourself and take the money, good luck to you. PS, I may post my poses as well.
