It would be down to the person in question as to his/her personal thoughts on the matter and whether they personally would consider it as losing ones virginity but personally i dont belive it would constitute losing ones virginity. I accept however, that it would be down to the individual and their beliefs on the matter.
I voted yes. Oral sex is sex. A virgin is someone who has never had sex, oral or otherwise. Chastity means no sex, period. Most of this discussion sounds like wishful thinking either from those who want head and are eager to flatter those who give it, or from women who are in denial about their virtue.
