Ttc bf is no help

My bf and I are trying to conceive and I told him we need to do it like every other day. He says he can't do it because he needs to build it up?!? Wth How are you going to tell me you want us to have a baby and not work with me on it. Build up?!? He keeps saying its me because he doesnt understand why we're not pregnant yet when we're not using protection and he's giving me all his "babies". I tried to explain it doesn't work like that for all women and sometimes women have to try. I don't understand.
