I believe you need to ask him why he feels he needs for you to do that? It sounds like he doesn't feel comfortable about himself. Virginity is a part of you. And what does being overweight have to do with it? The thing is this: If you have sex with him now; His main concern will only be about the sex. It's not going to be about you because he will imprint on the sexual experience and try to recreate it every single time he has sex. And that is something that will last a life time. That how men are designed. It will psychologically impact him and will change him.
Omg I have the same prob, I usually stay on the body, but when I ride he's to busy moaning and pulling my hair to notice my overweight body
Don't worry about being overweight... that's a nonissue for me. I lost my virginity to an overweight girl and I dated her for over 2 years and have no regrets. As for "the quality of your ride", believe me, he won't know any better, so just let yourself go - be youself and have a good time and I guarantee, both of you will have a good time and be happy. Happy Cherry Picking!
Maybe you are not the best. but how would he know? It's his first time, it's going to be plenty special for him. Don't beat yourself up too much with this. Just do your best to please him and it will be a great first time.
