My fiance sex drive is too much for me..

My fiance always wants to have sex. His sex drive is threw the roof and sometimes I can't keep up because I'm either tired or sore ( if you know what I mean). Don't get me wrong, I love the sex. It's just that sometimes I feel like a sex object instead of the love of his life. We can't even watch tv together without him trying to have sex. What should I do? Should I talk to him about this?
