My sex life has developed, as they all do through the years, to a balance of three aspects.
--I have regular sex with my wife, maybe about once every week or two. Not enough, but then... there are so many things that get in the way.
--I masturbate. Who doesn't? I've been enjoying documenting it on my personal webcam and watching myself. A somewhat fucked-up if hot way to "enjoy" sex beyond the main urgent orgasm moment of it. Actually watching myself play with my cock, how I move, how I look at myself. How I look. A study in masculinity, exposure and transgression.
--I give my wife oral sex. This is become somewhat separate to the first category, not that there isn't some pussy-eating involved, often in a sexual encounter with her. But due to time or energy... or age...sometimes doing what we can, what I can, what works quickly and without a full commitment to every point around the world ends up being simply an excuse to mouth-fuck her.
It's a version of a quickie. I love to do it and she loves to receive, and it's hot for its own transgressive (your face is down there?) element, an almost pathological willingness on my part to please and also the ongoing negotiation that has developed over the years. "You don't have to fuck me, honey. You don't even have to suck my cock. I just want to lick your pussy for a while."
I almost never get a "no" from that.
We do that once a week, more often than the full fucking thing. And it's often enough. I get hard, she sometimes gets off (or will the next time). It's foreplay that will pay off the next time. (Nothing like keeping her horny and cumming through the week, in anticipation of the main event in a couple days.)
And if we don't fuck, I'm primed as well and a couple days later if we aren't looking like we're going to fuck, I just jerk off and edge. Sometimes I cum and it's maybe as good, since timing, as having balled her a couple days before.
I know my limitations, and I know hers. And I know what she likes and what I like.
