When having sex with your spouse-partner, do you look her-him in the eyes, or watch the physical action? We look at each other some, but mostly we like to watch the in-out penetration. The visual helps stimulate the physical.
I like a little of everything. If we're that close and kissing and whatnot, I'll close my eyes. Otherwise we'll look each other in the eyes. But its fun to be upright lookin down at what's goin on too. Just like positions, this is a real subjective thing for us that changes with the mood
When I am going 69 I don't. She never watches me while she is blowing my cock. I watch her when I can while eating her pussy.
It's fun to watch what you are doing to and and with each other. And have you ever set up your camcorder and then watched yourselves on video. Very arousing. It can be difficult watching the whole thing because it inspires action together while watching and you lose track.
