I just want to understand why she doesn't feel comfortable to me, if she doesn't like me. why she give me her mail and number and tell me can chat with her whenever I wantMaybe... Just maybe... Because she's annoyed?
She told you she doesn't like to get naked, dude. Can't get much more straight-forward than that. Forget about it and move on, there's nothing else you can do about it. It's her body and she doesn't have to show it to you just because you want to see it.
