How can anyone not want and give oral?

Rosie and I were baffled at Wendy's comment. She does not give oral, that is NO. And she squirms at the thought of a man eating her out. So? You just do straight FUCKING? No foreplay? She did not reveal if she lets a man finger her.

There are some women out there that either don't want to give oral or receive it. But BOTH? Very very odd....
