Personally, I get turned on by knowing my husband is in bed asleep while I read posts on here (he visits the site too).

Then, when I am supremely turned on, I will go over to him and gently rub him so he gets hard without waking up. There's nothing that excites me more than having my husband wake up when I'm already riding him.

It's a little difficult keeping him asleep while getting him hard, but when I manage to do it, I get extremely turned on.
