Small Advice Please!!

Brittany
I..cannot seem to get my boyfriend to believe that I am really into the sex that we have. I just don't know how to make it any more believable..he makes me moan and move and want to do sexual things not feel the need to. He says he feels like an animal in the worst way because I can't seem to make him believe that I want him. Anything I'm lacking in? Anything I should do?? I know it isn't very..major..but I could really use the advice..thanks so much for any advice. A little goes such a long way!
