Who's a virgin, and who’s not?
Most people would say that a virgin is someone who's never had sex — and by "sex," they often mean penetration of the vagina by the penis. This dictionary definition sounds simple enough, but it leaves a whole bunch of people out of the picture.
There are a lot of straight people who don’t think of themselves as virgins because they’ve had lots of other kinds of sex, like oral sex and anal sex. And then there are all the lesbian, gay, bisexual, and transgender (LGBT) people who may never have penile-vaginal sex, but who hardly think of themselves as virgins.
Many people define sex in broader terms. For some, "sex" means vaginal, oral, or anal sex, while for others, it could mean mutual masturbation, manual stimulation (“hand job”), dry humping, or using sex toys to penetrate the vagina or anus. Lots of people feel that they "lose it" the first time they share an intimate sexual experience with someone else — not simply the first time penetration happens.
Some also believe that people have to give consent to lose their virginity — that virgins who are raped, for example, do not lose their virginity.
