I will admit, yes i have had sex, and no it did not ruin me. if this "man" is disgusted by you, then that's his problem. didn't you say that he initiated it? If you BOTH felt like sex before marriage is wrong, then he was in the wrong just as much as you were. I don't see why neither him or your friends are not talking to you, that's just not right. Are they Christians? If so, they should realize that everyone makes mistakes and that no one is perfect. Its not there place to judge you, so just ignore them, if they are going to ditch you over a mistake, then they are not friends worth having.
