I guess it depends. I mean yes be fair. If they won't go down, then you don't go down.
But at the same time, I have been with men who love going down. I mean they love it, they would be down there all night if you let them. Now don't get me wrong I love giving it as well, but I am not going to stay down there all night. Ya know? If he likes to be down there then let em. But just because he stays down there for super long periods does not mean I will.
