My wife doesn't like it at all. We've done the pineapple approach, but she has this thing about any odd textures, food or otherwise. That's ok, I don't feel somehow rejected just because she doesn't like jizz. I never ask her to go down on me, but she has done it a few times just to give me a surprise
She says she feels guilty sometimes when I go down on her, but to me they are not the same act and shouldn't be compared like that. I tell her never to feel guilty, I'm enjoying it as much as she is! Haha.
