My and my love absoutly love anal sex. He would prefer it everytime we have fun, but I do admit you must be in the mood for it. He always does the finger test and it's not happening that night he knows right away with a sound from me. I do try to give it to him everytime he wants it because I love sex and I don't want him groaning at me when I want it. When done right it does not hurt that bad. As most of the reply's have said - You must be in the right mood for anal sex.
As far as duct tape - I agree with everyone else.
