he isnt turned on cause some guys just detest everything about giving oral to a woman, the smell the texture the lips and all, simple as that, if you think you can make every guy into an eager pussy eater you are just too caught up on your pleasure and wont see that again, some guys just hate it, and there isnt anything wrong with it, not all guys have to like it, as for example not all girls have to like anal. In my case i love to eat pussy, and ass, love the smell the taste and can do it for hours. different people different taste for sex, thats all
