Aw, man. Trying to detail everything I like would be like trying to spec out a Diablo III character. Sure, some things are more common than others, but there are those hidden gems that are fun to play even if it's not how you plan to finish the endgame.
I...don't feel comfortable detailing my preferences, so instead I will mention some of the things that don't trigger lust.
Butts. I can see how people go nuts for 'em, but shape/size/width doesn't make my jaw drop. So long as it's big enough for me to squeeze or smack once in a while, that's good enough for me.
Lingerie. Just don't see the point to it. I'm always going to be more interested in whats in/under the clothes than the outfit itself. No sweaters, french maid outfits, nor stockings for me. Corsets are interesting, but more for what they do than how they look.
Perfume. There are a few scents I associate with fun, but the majority serve just to make me avoid you.
Ornaments. A few are nice. A handful will raise an eyebrow. But if the quantity of piercings/tattoos/scars/branding/implants* reaches the point where it ruins the overall body image, then I start to lose interest.
Voice. Dirty talk does nothing, and I'd rather not date Harvey Fierstein.
'tude. I'm not in it to rule, and I don't expect to serve, either. There will be a balance or else I'm gettin' off the teeter-totter.
Friends. Not interested in threesomes. Of any sort. There, I said it.
Porn. Most of it sucks (in more ways than one). Erotica is one thing, but watching other people find creative ways to pl*y p*nball is eye-rollingly distracting. Also, I'm not interested in recreating your favorite scene.
