Just what are you on about. People have preferences. Sexual attraction, which is important. If I want to discuss Wittgenstein's works or current politics - I have friends for that. I don't sleep with my friends.
I'm 5'11 and I dated plenty of men shorter than me, that's not a problem for me. But if someone 5'10 on paper would turn up as 5'4 in reality - that would be a problem and I wouldn't even go anywher with him, I'd just walk away.
Also I'm very slim and like my men of similar stature to me. Just as men, who prefer shorter and plumper women wouldn't like me (and that's perfectly fine with me), I wouldn't like fat men. I couldn't have sex with a fat man, it grosses me out. No sparkling personality would convince me to go to bed with him.
I'm not on the apps. My brother was not long ago. He's relatively tall, athletic and very outdoorsy. He wants a girlfriend similar to him. One came: short, way over 100kgs, couldn't walk without panting and stopping to rest often. About size 12 on the app.
Another didn't look anything like her photos, he didn't recognize her.
He met his current girlfriend in the real world. And he's not shallow, this girl is not a supermodel, doesn't have a spectacular figure or anything, a normal, 'next door' girl. But she's sporty, slim, outdoorsy, they have other interests in common too.
