What to do when your partner doesn't want to have sex

My boyfriend and I have been dating for nearly 4 years. For about the last year and a half we have had little to no sex. I used to try to initiate sex with him, but was always turned down. When I turned to friends for advice everyone had the same answer: he is either cheating on me or he is gay. I know for a fact that he is not cheating on me. We have also had an in depth conversation about his sexuality. I have asked him over and over to seek out therapy or get some kind of help so that our relationship can thrive sexually, but he has yet to do so. I have tried everything, but nothing appears to work. What should my next move be?
