BabyGurl, If your virginity holds any value to you, this is definitely not the way to protect it and you should stop these games NOW!
Technically you are a virgin when you have not had intercourse yet. Intercourse is described as having his penis inside your vagina.
You may or may not have a hymen that is in the vaginal opening. If you do have a hymen, it may be painful and bleed the first time anything big enough to tear it goes into your vagina. You may also not have any blood or pain the first time.
You are definitely not sexually pure any more. In many cultures sexual purity, the hymen and virginity is considered the same concept, but it is not really. You can be fingered, had anal sex or oral sex and still be a virgin but not sexually pure. You can have no hymen and be as sexually pure as can be.
Ask your boyfriend to please not do that again. You have the full right to approve or disapprove what he does and he kind-of sneaked that one in behind your back. He might think it is ok because you did not stop him but clearly, you did not even know what he was up to.
At the very least he should wear a condom if he gets his penis that close to your vagina.
