I don't seek out young women in their early 20s per se, but I've had great chemistry with some of them (I'm in my late 50s but don't look it, although I feel it lol). To me, it's the touch, not just the vintage or look. It's also her brain.
Due to me being middle-aged, most if not all are younger than me, but that's a range of early to mid 20s, to 40s, but the most representative age range of the ladies I see are between 30 and 40 I guess (a couple in this thread, you know who you are *wink* *wink*). There have been some that are even older (recent example, Eve from Ottawa,
www.atasteofeve.com, who's a gorgeous lady). Some of the regular mature ladies are MarlaGFE, MilfAlex, and Tori Sloane (saw her recently - wow we squeezed 90 minutes of fun into an hour, whew!) Just recently I corresponded with a mature SP who went under the name Agent Provocateur (gorgeous buxom blond).
I can also understand why certain men must see younger woman (they may be older and married to someone their age, and therefore, yearn for someone they don't have and miss).
I've also experienced being with GILFs (either in the industry or civilian world), and that vintage doesn't take away from sexual prowess (I think it's a bit fetish freaky too).
