A big veiny dick? Heavy breasts? A slim figure? A big dominant man, rippling muscles and a square jaw? An hourglass figure with curves that water would just slip off?

So…. yes. Being a bi guy, all of that. All of it!

women being open about them liking sex. them being carefree and horny gets me going, I'd be down for pretty much anything with a girl like that.

This woman right here, Alejandra Guilmant, has the ideal body shape for my taste:

Slender with large breasts and a round medium ass are ideal. ("How original! Daring today, aren't we?")

That being said, I feel like I'm capable of appreciate a super vast range of body types. Which potentially poses problems for monogamy down the line. I'm only into women.

Pear shaped women are also very attractive to me, for instance.

Being open to many body types allows you to be more governed by beauty and fashion, so i guess that's what "turns me on" (i.e what I notice) about people in the wild. As long as you have a healthy body (which includes some "overweight" people) you can make your figure look good by dressing in a way that compliments it.

Also, little cues and behaviour. Loud mouthed people who seem to be ignoring you/don't see you as a mate are a turn off.

I'd also like to mention that I very much like mom bods, like you mentioned. Probably spent as much time lusting over adult women in my teenage years as i did lusting over people my own age, and that attraction to "milfs" is still there today. Seeing a woman taking care of kids is attractive, weirdly. Sometimes even a turn-on. But i think that's more about "proof of parental capabilities" than "oh she's a milf, me likey"

Skinny frame, small areolas, cute nose—which can vary wildly and is utterly subjective.

Beyond that, tall or short, blond or black haired, big tits or flat chested, it’s all just icing on the cake. Even 2-of-3 of the above will generally make me rock hard for you.

Honestly? Enthusiastic consent. I can overlook physical features that might not be my favorite if she's enthusiastic and direct about what she wants in bed.

My wife is on the spectrum, so unfortunately while I know she is enthusiastically consenting in her own way, from an outside perspective it would seem like she's not at all into it.

Her version of enthusiastic consent is, "if I didn't want to do it, I wouldn't." Which is fair, although it does cause me some anxiety. And yes, we've talked about it and she's working on being more obvious about it.
