Oral is not sex. Having sexual intercourse (for lack of better words) is putting your penis into a girl's vagina. That is sexual intercourse, and is how you lose your virginity. Oral is not sex.
How the hell oral sex is consider real sex?? Sucking dick is not sex it just sound better by calling it "oral sex".
For a second you make me think that if a girl sucks a dick her mouth is not virgin anymore... just like ass.
Who the hell cares? Of course it's not "sex", that term is reserved for sexual intercourse. It is a sexual act though, and engaging in it means a loss of virginity. Losing your virginity doesn't mean vaginal penetration, it means breaking the "seal of purity" on your sexual history. Once you've engaged in any form of sexual act, you are no longer a virgin. That's all there is to it.
It's like opening a bottle of Snapple. You may not drink the whole damn thing, but the bottle has still been opened, and as such, it's purity has been compromised.
So if a girl gives you a hand-job like I said before, its sexual, so you lose your virginity? No, same with oral sex.
Your analogy would work if your saying, if you start to have sex, but don't finished you still lose your viginity. You used 1 thing in your analogy, the one drink, and you are refering it to 2 things, sex, and oral.
