One thing I’d add is that if you match and have a nice chat don’t rule them out on looks alone. The ones you think are ‘your type’ often don’t live up to it when you meet in person. And conversely if you get to know someone you may find them more attractive in real life than in their pics.
My DP is conventionally good looking - ie tall, slim, has all his own hair etc! But I was looking for stocky bald guys as that’s more my thing 
. He sounded interesting and could string a sentence together, unlike many of them. We met a few times and I still didn’t really ‘fancy’ him as such, but eventually we kissed, which was nice, although no fireworks. It wasn’t until we finally made it to bed that I felt it!!
So I’m not saying sleep with men you find repulsive, but if there’s even a flicker of “this is a good man who has all the qualities I want in a partner” give it a chance as the attraction can grow.
My friend passed up a guy who was perfect for her, had a house in Spain with loads of animals (she rescues dogs from abroad and loves animals), he made her laugh, was confident enough to challenge her and she’s quite bolshy so she needs that, but she didn’t like his car and he was too short. So she ruled him out. I was so annoyed at her! I know you can’t force attraction but you can give it space to grow.
At our age none of us are getting any better physically, so making that the most important factor is just silly.
