If you were willing to roll with the toddler crawl then I doubt your expectations are too unfair. Sounds like you were pretty tolerant to me!
When online dating I generally see who makes my eyebrow quirk as I look at their eyes & see if they have lips I want to kiss.
If someone makes my nose chime in & show revulsion I don't bother, it's a first reaction hard to get past. No matter how awesome they may seem, the nose knows what's up & I want someone I can cuddle & kiss so we can get to the good parts like getting to fall asleep with someone's hand on my ass, but that's never going to happen if my base instinct is repulsion.
Online dating is so hard I had to give it up. It started feeling like a self esteem killing job & I hated that sense of not having the time to give everyone a chance. I started prioritizing the people who came around when I was looking for a person & seemed to be on my timing instead of forcing things, but I think my attachment style is too over the place to let anyone get attached.
Good on you for trying to get out there! At least he was the weird one & you're not the one that has to look back & wonder why it didn't work.
He's probably going to cringe so hard when he realized he was really crawling on the floor.
