I've taken some time to think about this. I personally identify demisexual, but I think I'm more drawn to men if only because I take a lot of liking to more alpha personality types. I have issues with trust, but I really find myself more drawn to them and able to trust them with intimate details. Women could be this as well, but I personally see this kind of attitude more in another guy...
Anyway, so here it is- I like taller, and leaner/stocky. Taller is easier to hold onto and rest on, and leaner means they take care of themselves. Stocky would be the same thing, only a bigger guy, which is fine. As long as they aren't carelessly overweight, or straight up ripped. The former makes me think they don't feel highly enough to try to take care of themselves, and the latter is just plain frightening. I would never want to be near a pissed off ripped guy. Even if he's just as soft as a teddy bear, even if he's not angry at me... a ripped guy is just terrifying to think of as angry at all.
Not hairless, but I don't want them even remotely to a bear. Not that much a fan of hair not on the head, but if it does grow, as long as they trim it should be fine. The last physical traits that really matter to me is body health. Smokers and piercings scare me away. My family has a bad history with smoking and health, and it's something I hate worrying about. And piercings, well. I can tolerate ear piercings and nose studs. Once I start seeing rings not on the ears, or holes in other places, rings, and ESPECIALLY stretchers, I cringe horribly. I can't deal with seeing things like that- they look too excruciatingly painful, and I will have to keep thinking about it like that. Tattoos and inkings are okay, but not piercings.
But now comes the important stuff. He should be about my age, and if not, not too far off. He needs to be patient, gentle, understanding, yet assertive. Someone who gets that I like to talk and think things over quite a bit, but can remind me to get my head out of the clouds when I need it. Aggressive or dominating as traits don't quite fit. I don't like being demanded to do something. Instead, I like discussing why something is logical to do. Someone who can think from the angle where everyone benefits, instead of their own agenda. Basically, I like direction, not walled paths. A gentle push, not a forceful shove. I like the thought of giving the power of choice to my lover, while being able to have enough override control to veto something that makes me uncomfortable.
In short, someone who I can trust more than anyone else, someone I have zero doubt will not abuse or walk away from the trust I give to them.Of course, this is just me dreaming away at the thought of my oh-so-perfect man.
