I have done sex 2 times with my boyfriend now he don't want to marry with me can I get marry with other guy

I suspect this question was asked because of cultural differences and may be better asked in a different forum.

In most of the world, there are no legal prohibitions that one must be a virgin to marry. However, some religions do have such prohibitions (I believe). So you need to clarify your question to include the context you are asking it in.

Of course you can marry another guy, don't worry about it.

(NB. If she was in one of those cultures/countries/religions where they are extremely strict and outcast you from society or even stone you to death, she wouldn't have had sex before marriage in the first place.)

That's how I see it anyway.

Yes you can, but any further sex should be after marriage if it is a cultural concern.

I agree with the others though, as if it was a concern, you should have waited until the promise of marriage was made a reality.
