Relaxer: Why aren't you interested in women in their fifties? Those in their early fifties are closer to your own age than the 26-35 you target.
If you're just looking for something casual, I would think the early fifties would be gold. Single women that age have already done the relationship and kids thing, or if they haven't probably have no desire to do so. Hell, you might even get some free meals and other free shit out of a gig like that. Or heck if you're going to insist on married women, you might even get yourself some kind of cuckold situation...that way you don't have to worry about the husband tracking you down and knocking your teeth out.
Whereas women in the 26-35 range are typically husband-hunting. And if they're looking for some casual action, they're more likely to look for it from a 30 year old hottie than a bald 45 year old (giving you the benefit of the doubt here) hottie.
