Recently, my boyfriend and I have engaged in sexual activities. Not sex, but just touching & rubbing of the genitals, etc, as we are too young for sex, or anything. I was touching my boyfriends penis, and there was this liquid there, and I have no clue what the hell it is. His penis wasn't erect or anything, so it couldn't have been sperm, so I have no clue what it could be.

Do you know what it could be?
