I guess everyone has their own communication style, and their moments. That said, I really appreciate seeing the other person is having just as much fun as I am, big turn on for me.
There is no absolutes for anything, some love, some don't, on both sides.
I personally really enjoy going down on a woman and really give her a good time, but as much as I enjoy getting a BJ myself I try not to count points if that makes sense, it takes away from the fun and feels a bit petty. I'm just happy to be invited downstairs and it tastes all the sweeter if I see it as one fun event rather than a 2 way transaction.
As mentioned above hygiene is a big factor too...
