Help: Relationship + Tights

Hi, I am in a relationship with a guy who's got a pantyhose (tights) fetish. I'm totally fine with it and wear tights regularly to turn him on. In fact it really turns me on knowing what gets him going. I've got my own fetishy aspects that I am open about. However, he never approaches me for sex, and admits that sex was only a real turn on for him when he was a horny teenager. He honestly said that he never thinks about sex. He used to get really turned on when we were first together and I wore tights..but I think it is less of a turn on for him now that I know about his fetish..as I think an important part of it is the voyeuristic aspect (of the girl not knowing she is being watched putting tights on etc) I walked in on him watching 'tights porn' the other day..even though I was just in the other room. Not to be big-headed..I'm an attractive-enough type. Perhaps this is just a case of him getting bored sexually with me, and a sign the relationship is over? Believe me the same thing has been happening for a long time, and I have tried everything to spice things up..we've made home videos etc etc..but I just know that he prefers to masturbate and be voyeuristic and get-off that way. He's a great guy and very very good to me..but I need someone who wants to be close to me physically. I feel so unsatisfied. Should I give up on this relationship?
