This my friend, is a plan for disaster. Never put someone's needs over your own. Everyone needs to feel comfortable, accepted and loved including YOU! You may give him the wrong message and it will take a toll on your self esteem. If the relatiohship is worth having then go slow and pay close attention to your feelings about the topic. It's up to him to feel comfortable and accepting of himself. If you don't pay close attention to how you feel then you will end up very hurt and the relatiohship will suffer. As far as understanding why he does it? Well you may never understand. That is why you have to pay very close attention to your needs and feelings within this relationship. This kind of relationship takes more effort than most and it's easy to get lost and confused about things so do not put him over yourself or you will most certainly fail. Just my opinion as I have totally been there.
