Some women will give head but don't like it, some won't, some love it. there are enough women love giving head that it's crazy to be with a woman who doesn't love giving head, or swallowing or taking facial for that matter. People's attitudes about head rarely change so if yours don't mesh move on and find that wonderful woman whose idea of a good night is sucking you off.
Maybe she doesn't want your gross penis in her mouth. She may have a texture thing....some people do. I don't give my boyfriend head unless he asks or unless he does it to me first. He doesn't really ask all too much....and that's FINE with me. The sex is good and that's the number one thing in the 'sexual' part of our relationship. He respects that I'm not bj crazy....
