the problem i have with that argument, is that I come across so many individuals 10+ who justify their sexual activities by saying they've never had sex before (anal/vaginal). Except, you can still transmit std/sti from oral sex. it's sex. It's not anal, or vaginal sex. but its sex. for some people its foreplay, for others, that's as comfortable as they get with sex (i usually see this in the male/male community).
I've come across individuals who thought that by refraining from having anal/vaginal intercourse and just giving oral sex they could prevent themselves from getting an std/sti.
So I dunno, I don't like the argument that oral sex is not sex. It totally is sex.
