In the beginning of our relationship he would always go down on me. Now it's been a yr and a half of being and living together, and he's gone down on me twice. He's told me that there's nothing wrong with my smell or anything like that. I've asked about hair on coochie and he prefers some hair, so I've been maintaining how he likes it. His answer was simply, he just hasn't. I don't like comparing, but I would like to receive if not just as much as I go down on him, at least some. How can I ask him again without feeling ashamed, or not receiving that kind of pleasure from him again?
