He will know because you will not bleed when he gets inside you for the first time. Usually on the first penetration, the hymen will break and it will cause bleeding. If your boyfriend won't like you any more cos you are not a virgin, he is not worth it because if he really loves you, he can accept the fact that he is not the one that you fell in love with.
he will be worried about "Dates"
Let him know you want to stay a virgin, and if he doesn't respect that then he probably shouldn't be your boyfriend anymore.
Ask
You ask her.
here's what u do u tell her how u feel and get to know her and if she likes u as a boyfriend then she will dump her boyfriend for u and really get to know her before u do anything else k hope this helps
To know whether a guy is a virgin or not is to either ask him or one of his close friends. You can't look at a dude and tell from his physical features if he's a virgin or not.
every girl is at some state of their life
You should tell the other girl and both break up with your boyfriend.
If he has never done it before you dont know if he likes it or not. Once he does it then you will know. ALot of guys like it but some dont, just depends on the guy.
There are no signs that a girl is a virgin, you'd only know if you asked her. There is no clear definition of what makes a virgin. Virginity is about valuing women who have not had sex.
ask her
Talk to him. Communicate. Let him know you know he lied & ask him why he felt the need to lie to you about being a virgin.
