It's not just tinder, its everywhere. Even in college I've had girls tell me I was too short for them at 5'8. Everything seemed fine when we interacted as friends but as soon as I started to flirt, they disappeared.
And just forget about bars/clubs if you're under 6'. Every time I go out I want to kill myself looking at the competition and getting no attention from attractive girls. So yeah women do care about height whether how much people on this forum want to cope by imagining that they dont.
All else being equal, yeah, taller is better. Why do you think LL interests me?
Yeah, bars and clubs, and online dating are not gonna be your friend at 5'8.
But dude, you're 5'8. That's only 1-2" under average depending on how you slice it.
There are a million other ways to meet women. Grocery store, church, walgreens, social circles, hobbies, front counter at hotels, pools, lakes, etc. I've picked up girls in all these places.
Casual sex is tougher at our height, no doubt. But relationships are easier. You know how many girls I've feigned interest in having a relationship with until I got sex and then dumped them?
I am just a bit under 5'8.
LL let's you change the hand you're dealt. If your gonna do it fine, I'm not saying don't do it. But LL won't drastically change your life with the attitude you show here.
Just relax man, it's not that bad.
Rejection is part of life as a man. Learn from it, embrace it. Do what you can to adjust yourself and reduce rejections (which might include LL)
But "height is life" as your profile says...is wrong. Its just one of many things that makes a man.
So no, no "coping" here. Height is important for sure. But so are many, many other things.
Play the hand you're dealt as best you can. Change that hand with LL if that is what you want. Just be smart about it. (good doc, not an extreme amount)
