not having sex

My boyfriend and I have been together 5 years. We take about having kids all the time, but when it comes to having sex it's like it just doesn't happen. I tried trying to talk to him about it, but I usually get half assed answers. I did get pregnant earlier this year, but miscarried 2 days after I found out. I don't if he's scared. I've offered to get back on birth control and he tells me that he doesn't want me to do that because he does want a baby. I stopped telling him my ovulation week because he says that puts too much pressure on him. Does anyone have any other suggestions? I mean at this point I don't even care about getting pregnant. I just want the intimicay with the man I love.
