Im m(18) lost my v card the other day to my girlfriend (19) and shes bi and experienced in both genders.
Anyway after probs like half hour of foreplay kissing and i gave her oral she got on top of me and i cant remember if it was 30seconds or a few minutes but either way it wasnt long enough before i blew my load and im concerned that next time its going to repeat itself and i wont be able to last long enough in penetrative sex for her we tried to go again later on but after like 40 minutes of foreplay i couldnt keep an erection up and then the third time i went down on her and then she got on top of me put it in but it hurt me idk why but then we stopped trying after that
