And to the guy that said that sexual intercourse is anything that can get a woman pregnant, not all forms of sexual intercourse get a woman pregnant. But, all forms of sexual intercourse can spread STDs. Yes, kissing spreads mononucleosis, which is an STD.

So the thing is, if it can spread STDs, then it is sexual intercourse, regardless if it can get a woman pregnant or not.
