you have to ask yourself if you trust this guy, how long have you been with him, is he a serious boyfriend etc.. if it's someone you don't know that well yet, i would say use condoms as men would say anything for a shag and you might not know where he has been before you. i would say use condoms for ages until you fully trust him. it is very easy to get sti/stds through having sex whether it's for the first or 100th time! take care

i am the guy lol...but thanks for reply:)
