How are you doing for birth control, on the Pill? IUD? And what do you intend to do if this guy is a player and gives you an STD?
It really does not sound like this is a committed relationship, do you intend to have sex with him on the theory that this will make him want to be your boyfriend? Please be realistic, why would he want to have to commit if he can just come over and use you for sex and go away again?
I'd save the loss of virginity (being a virgin is pretty neat) for someone who loves you and can hardly sleep at night for thinking of you and who wants to be with you all the time whether or not you are having sex.
AT THE VERY LEAST, use condoms. Pregnancy at 16 is a whole can of worms you do not want to open, and STDs can be very serious.
Just know that you don't have to have sex either. He's just a guy you like... Is he your boy friend? There's no reason to have sex with him if he's just a guy coming over.
You don't want to give up your virginity to a guy that may not even want a relationship with you. That's important too....
About your question, it may come out after sex. But as the other person mentioned, you will probably bleed anyway.
there is a possibility you bleed because you are a virgin so maybe anyway blood can come out
I meant *wants not watchers ^^
