Bad sex...

Jasmen

So I'm currently engaged to the love of my life. He respects me, cares for me, and I never have to want for anything. Even when we disagree we laugh with each other. We've been engaged for some time now and everyone keeps asking us what's the hold up. I just respond "weddings are so expensive and we want to get our fund together" or a similar answer. Deep down I know the hold up is me. When we make love I feel like it's a chore and not an intimate moment. I feel sometimes if we don't have sex he'll be unhappy but I'm not happy while doing it. I tried to coach him and make it fun, I've tried telling him but he just gets offended. I don't know what to do?!? Help....
