As the title says this would be my first sexual encounter and it’s with a f23 and she is plus sized which I adore. I’m kind of facing an insecurity because I don’t know if I’m quite big enough in the down stairs department im quite average exactly average if you look it up idk if I can specify the size but yes. She has a big butt so idk if I can satisfy her with back shots ya know maybe missionary. I just feel like some positions just can’t be done unfortunately since my size isn’t big does anyone have any tips or advice?
