So last night after the most perfect day ever, my boyfriend and I had mind-blowing car sex. This is a first for us because it usually always goes terribly wrong but last night ....

Anyways. We were switching positions and he pulled out. My vag just seemed to suck the condom up. Again when he was finishing he pulled out to ejaculate but the condom stayed inside of me and he ended up finishing on my butt. Although I am on birth control we still both feel like we should use condoms and not take any chances. Why does my vagina keep sucking up condoms? What do I do or what can he do to stop this problem
