Today I went to a sex shop and bought some condoms. Before this, I touched some of the sex video tape boxes, while looking at them at the store. I saw the guy at the counter had a tattoo in a hand, and touched the condom box to put it in the bag.
A few hours later, I masturbated at home, and before putting the condom on, I had already touched the tip of my penis, which already had secretion. Then proceeded to masturbate with condom till ejaculation. STDs from this?
