Sure! Both actually.
While I’m not into men, I am into dominance, and can enjoy some things with men in that context, so I’ve done most things you can do with other men.
Can’t say giving a hummer worked well. The extra concentration needed took me out or the right headspace to ignore that I was with a man, so I couldn’t focus on what I was doing, if that makes sense.
I’ve gotten quite a few though. I can’t say they’re better than head without the vibration, but they are definitely different in a pleasant way.
