My friend is acting really weird

She is probably disappointed. It is never what you expect.

Yeah she is acting weird either cause she likes what she has done and is bragging or feels very guilty whatever is don't comfort her... she made the mistake let her know she did.

Sometimes when you are from a family with traditions or religious beliefs it can create this feeling of guilt or shame? I am not saying that is the case here but possible. It also could be just a time of adjustment to being a woman and not a little girl anymore. I suggest that she talk to a sex expert, dr (gyn), or her parents if possible and just get a more in depth realization that it is not going to make her any less of a person and she is ok!!!
