My 22 y/o friend recently told me she has a crush on her 18 y/o colleague. He is a very young looking 18 y/o (I've met him) and could pass for 16. She says she has fallen for his funny/charming personality and is attracted to him physically too. This is confusing for me, I know legally there would be nothing wrong with them doing anything but it seems a bit weird to me. She said he has told her he is still a virgin and she has said (to me) she would like to be his first.
I don't know if I'm being out of line here or what, I just feel this is not an ok situation. Does anyone know what I mean/have any input.
