Phimosis? Anyone have experience?

So my boyfriend that I’ve been dating for 2 months now told me pretty early on that he has phimosis. It came up because he wouldn’t (and still won’t) let me touch his penis or actually really see it at all. I was trying to blow him but he wouldn’t let me so finally he had to tell me what was going on. I didn’t know what phimosis was at first so he explained it to me. His case is particularly strange I feel though…because he said all his life (he’s 22 now) his forskin has been attached to the head of his penis by a small piece of skin so he had never been able to roll his foreskin down until 8 months ago when he was having sex and the little piece of skin actually tore. To me that almost sounded like a positive thing because I was thinking…ok so now you can roll your foreskin down which is more normal. But apparently he says it’s like extremely uncomfortably sensitive to the point where he doesn’t trust anyone to handle it but himself. I like to be hands on with my partner as well and so it’s really bothering me that he won’t let me touch him or even really see him for that matter!! The other thing that concerns me is the sanitary aspect of it because he said he’s never tried to roll down his foreskin and clean inside. When I did try to go down on him once there definitely was an odor which concerned me. I just don’t know what to do or how to nicely bring this up. We’ve talked about it but I can tell it makes him uncomfortable and he doesn’t get the big deal cause he’s perfectly happy with how things are. He doesn’t crave to be touched or sucked so he’s content. My biggest issue right now is the cleanliness. I asked him to try to clean inside once which he said he did but he said he “couldn’t really cause it’s hard to pull down when it’s soft”. I’ve been with multiple uncircumcised guys before and they all knew how to clean themselves so I’m really at a loss of what to do without making him really uncomfortable or upset. Advice please!!!
