Well, that's a fine line, most do seem a virgin status related to actual intercourse. The basic virgin status biblically was a legal status regarding women, because a woman was property and her virginity had value, so many laws were given based on her virginity, these laws didn't apply to men.
However, these were hebrew laws for that culture. There have been many news stories out on teens today having oral and anal sex as not to get a girl pregnant and somehow girls thinks it protects there virginity...lol.
I think most people today deem oral sex...just that...sex, we don't say oral, we say oral sex, because body parts are used to bring sexual climax. One may not lose their virginity, such as a girl doing oral doesn't break her hymen. Seriously you could go on, the same with a hand job, etc...
Anyway, I could agree you can have certain types of sex and still remain a virgin. I can remember when I was about 19, I dated a girl seriously and we both wanted to remain virgins until we got married at that time. However, after about a year, our make out sessions we started serious body humping, enough to [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] for me and later used our hands. I never entered, ect...my reasoning was I didn't want to take her virginity. We later broke up, so I was glad for her I didn't.....but were we virgins...I would say so, did we have sex, prolly so in a way, it's really cutting fine lines."
One thing that people debate is premarital sex, biblically sex was money, the only difference in a virgin and non virgin seems to be value, other than that nothing much else is said regarding the premarital aspect of it.
"The basic
ketubbah of a virgin (two hundred maneh [one maneh=fifty shekels]) was double that of a non-virgin (one hundred maneh) (
Mishnah Ketubbot 1:2). Those who were divorced or widowed while betrothed but before marriage retain their status of virgin. This difference was doubled in the case of the daughter of a priest who was a virgin, whose basic
ketubbah was four hundred maneh (Mishnah
Ketubbot 1:5). This distinction emphasizes the value of virginity and the significance of sexual exclusivity on the part of the woman to her husband and, in the case of the priest, the value of caste status. A number of situations were described biblically which deal with the seduction or the rape of a virgin who is either unattached or betrothed. Consensual sexual intercourse of the betrothed or married woman with someone other than her husband would put both the woman and her paramour in the category of adulterers. Seduction is considered to be consensual but the cases discussed in the Bible according to rabbinic interpretation were dealing with minor girls who did not have the legal right of consent.
