Lately when I have sex with my boyfriend I get really nervous and it throws off the whole thing...I feel like i can’t seem to ride him right because I’m not good at doing it fast pace..which he likes...and I’m insecure about my breasts. Also I feel like I can’t even French miss him right either...I get nervous and mess up...it’s been so bad that today I stopped having sex and started crying. In the past we’ve been great...I have a big insecurity problem and I have a fear of a guy saying that I’m bad at sex. I don’t know why...why do you think I feel like this?
