Assalam alaykum.
Some muslim people say that in islam we can not marry a woman with whom we already had physical relationship. Please put some light on this.

Why Not?

And who are we?

You had sex with someone and took her virginity and now you are asking if you can marry her?

A Muslim Man will have sex with 10 Muslim girls and they lose their virginity to him. He then marries a Virgin,, what will happen to the 10 girls? Will they never be married?

If he can have sex with a woman and marry another, why can't the woman do the same?
