I'm 16, me and my girlfriend have had sex about 5 or 6 times now, yesterday we went to have sex but as soon as I put on a condom I couldn't get it up, it was really frustrating and embarassasing, any ideas why this could be?
chalk it up to nerves...its more likely to happen next time too if you dwell on it too much...relax...enjoy, but don't ditch the condom in an attempt to remain hard.
