In my 40s and I'm all over the spectrum. I like young, old, short, tall, thin, curvy, cis, trans, blond, brunette, red, purple, whatever. I'm at the point in my life where I've been involved with or crushed on women of all races and sizes. Context/story/set-up matters more to me than anything at this point. I can think of dozens of instances in my life where I met a woman like a friend or co-worker and she didn't immediately jump out at me but spending just a little bit of time around her made her irresistible. Having the tomboy best friend that shows up to the house one day in tiny shorts and you suddenly start thinking about her differently, which is an experience that I'd love to see replicated in VR but it feels like it will never happen.
The only thing that really turns me off at this point is the giant fake tits and duck lips. This means the selection of older women in porn is extremely slim because that's become the default MILF look, so I suppose that makes me gravitate more to younger newcomers. But even then it feels like just a matter of time before most of them come out of a doctor's office with cross-eyed balloons on their chests and I'm left wondering what the hell they were thinking.
Big tits, no waist, no ass was big in the 90s. Back then I was watching Private blockbusters that had huge budgets and natural women with actual storylines. That has absolutely influenced my tastes and what I still look for now.
