My bf stuck his penis in me about half way b4 i made him pull out due to pain. i started bleeding a lot does that mean i lost my virginity?

No: No. Virginity is a cultural and even superstitious construct. He probably did not get through the hymen. You did not have the experience of first intercourse, which is usually wonderful. You're young & i understand why you'd want an answer. You may want to talk about this event with your physician, & if you think this is the right guy, work together on other ways to express your love 4 each other.

Sorry.: Yes, it does sound like you did lose your virginity. I would recommend in the future you use protected sex and check with your doc about getting vaccinated against hpv.

Sounds like it, but: It sounds like virginity is lost (bleeding or no bleeding, it makes no difference), but surely one is exactly the same great person 5 minutes prior to the penis event as she is 5 minutes after the penis event. The lesson here is that the virginity issue is a man-made issue (or woman-made issue) but really does not change a person's true inner self. Avoid letting anyone make a big deal of it.
