You two are hurting one another. Honestly, some counsellors will tell you that when you realise a sexual incompatibility of that magnitude is present, the relationship should never have gone past the dating stage. Fact is you two are not sexually compatible, and there is nothing wrong with either of you. You like what you like. He likes what he likes. Unless there is a happy medium or compromise, it is not going to work.
I totally agree but I think the chances of a happy medium are out the window.
