relationships

I've been in a relationship for over 5 months and in the beginning I would feel butterflies whenever I was with him or he would kiss me. Now I feel that all he wants is sex. He said sex was an important part of a relationship for him. He feels that it's very intimate. My feelings are not all there anymore, I see him at least 2times a month & the most once a week. I feel that plays role big time I also feel that I am falling out of this relationship. I still care deeply about him & I would hate to see him with someone else. I don't know what to do.. any advice on how to keep this relationship going & get those sparks going again?
