hi,
i did this to my girlfriend and she wasn't sure about herself to, but i will tell you from a person that is willing to do that they like how you look and they dont mind. He told you that he didn't mind so you know he doesn't mind. but the main thing is if you dont feel comfortable with it then just take it slowly and sooner or later you will be fine with it. and about the shaving thing, i tell my girlfriend not to shave, i dont like it, if she trims that is ok but i will not like it if she shaves because it feels like you are doing it to like a 9 year old, so actually i liked not shaved. i hope i could help.
