How to lose male virginity without sex?

Can't be done: By definition. Exactly what you want to consider "virginity" is up to you in your cultural context. But by definition, losing virginity involves having sex. It may even be defined by body part, type of partner, or whatever. Truth be told, you'd do well to talk with a sensible older guy -- maybe even dad -- about your developing body, stop worrying, nad save the best for somebody truly special.

Wrong question: Definition of virginity is person who hasn't had sex. In my opinion, sex includes oral, vaginal or anal sex, but does not include masturbation.
