I've personally been looking for a more long term styled relationship since I was about 9. There's a whole story behind that but this might already be long enough of a response.
Honestly, my answer has changed a lot over the years. These days, it would be someone who cares enough about me to see me as a potential partner and who also at least appreciates my interests, passions and hobbies, if not sharing them. Looks do matter, however there are exceptions. Like I'd be down to be dating someone who was on the larger side, IF they were doing things about it. I was larger than I currently am but I'm also still working on it. I don't like how body positivity has tried to brainwash women into believing that they're TRADITIONALLY attractive when they're obese, when it's clear that's not the case as I never had any women coming up to me when I was obese and telling me how drop dead sexy I was.
I'm definitely not perfect, but I'm also not horrible. I work hard and I conscientiously try to conduct myself in a respectful but also entertaining and intricate way that would be appealing to women. I honestly do believe that my personal type just doesn't fit with the women that I persue, at least so far. Universally the response has seemed to tilt in the direction of, "they aren't attracted to me." Problem is I've never gotten a straight answer in regards to this criticism. It feels like at the very least some women don't really know what they want, yet simultaneously whatever it was, I didn't provide it. It's frustrating and gut wrenching, particularly if they end up dating a guy who showed less commitment than I did. I've come to learn that that's actually a thing women do so I'm not beating myself up about it.
I've never actually been on a date in the nearly 27 years of my life and on the wrong day, that thought absolutely destroys me. 9 year old me would have definitely cried if he knew every detail of the next 18 years as a ghost in the dating world.
I'm honestly a hair's breadth away from closing my door and saying, "The dream I had of finding that one person that you can do everything with, share everything with, build everything with, enjoy everything with, transform everything with and love is such a wholesome, inexplicable way that it literally intensifies everything in your life; that dream doesn't exist anymore. It got mutilated, marred and entombed on the battlefield of modern society. There is still a tiny amount of hope in me that is clinging on to life support. I don't know how much longer that will last before I close my door and say, "Too late. I wanted to grow in my youth with someone, not have someone come along after I've already built everything all by myself."
If I were to give one piece of advice for women, it would be to show more care to the men that interest you. Men proactively show care to women every day. For me at least, it almost never feels like it equally comes back.
