No sex in 6 months?

My BF and I have been together for 4 years. Our sex life has never been spectacular. He is a good guy and we have fun together and he is dependable though. IN the past we have gone long periods of time without having sex and I’ve asked him why but never get a real answer. So this time I’m not asking why, but we haven’t had sex in 6 months now. In bed he may spoon me,but I’ve noticed him cup his private area with his hand sometimes when we lay side by side. In addition he has never been overly affectionate. I just don’t know how much longer I can deal with this. I’ve never dated anyone like this in my life. Advice please?
