Your bf tried to put his thing inside you but he didnt put it all because you didnt let him does that mean im still a virgin?

Well, that depends on how you define virginity. If your hymen was intact and did not tear, which would have resulted in bleeding, then scientifically you are still a virgin. But this is complicated by the fact that your hymen may have been torn from nonsexual activities when you were younger, such as horseback riding or a bicycling, or other nonsexual things. So, you can't fully go by this. I guess the bigger question is, do you want to be a virgin? It sort of sounds like you do, and so then, I would go with YES, you are still a virgin, as you did not complete the sexual act with your boyfriend. But, dear, be very careful, because you can get pregnant from even such things as 'just the tip'. His early seminal fluid (aka, pre-come) can contain sperm, and one of those guys can swim right on up your vagina and meet an egg. So, if you are engaging in ANY sort of sexual activity involving his penis near or around your vagina, it is best to protect yourself and your partner by having him wear a condom, to help prevent disease and pregnancy.
