I'm 4"11 and he's about 5"2 5"3...he also a younger, I'm 18 and he is about to be 17. We were having sex and I just wasn't feeling it, he is too small.!! Don't get me wrong, he is such a great guy.! Sweet as can be and very handsome..yes sex is good but can do with out, I just don't know what to about this..how do I tell him, how do I satisfy him while trying to satisfy myself as well.?!? I don't wanna hurt his feelings.!! PLEASE HELP.!
