Me and my friends were arguing over this and it seemed to have a split, with males feeling one way and females the other. Here's the situation: A guy sticks it into a virgin "just to see how far it goes" only one time. Is this sex? If not, is the girl still a virgin? Can you not be a virgin but never had sex before?
If it goes in, it is sex and she is no longer a virgin. The math is fuzzier for oral, but the situation you described is sexual intercourse. Definitions follow from dictionary.com. Sexual intercourse Coitus between humans. Sexual union between humans involving genital contact other than vaginal penetration by the penis. Coitus Sexual union between a male and a female involving insertion of the penis into the vagina. So, according to dictionary.com, even oral is sex.
whatever the women say, just agree with them they have 100% of the thing you want, and this a time to be result oriented
