TTC Question

My husband and I are just starting this process. I'm nervous to post this because I know everyone thinks that ALL men just want sex constantly, but for us it's only 3-4x a month and I'm wondering if we time it right if that will be enough for a BFP with time. I know it's different for everyone and it takes time, but it just seems that when people say they are TTC that means they are BDing constantly.
