That’s gotta be wrong, because almost all the men I know who are under 5’10" still managed to get laid and/or married.
Let’s look at a few extremes, shall we?
Peter Dinklage is 4’5" tall and he’s married. With a kid.
Warwick Davis is 3’6" tall and he’s married, too. With two kids. And he doesn’t have a problem with his 4’1" wife being taller than him.
Verne Troyer, who is 2’8" tall, was filmed by papparazzi while having sex with his live-in girlfriend in 2008 so even if he’s not married he’s still getting some.
Dude, if THOSE guys can land a girl so can you. Wait, you might say, aren’t they well known actors? Well, yeah, they didn’t just sit around feeling sorry for themselves, they got on with their lives and, oh surprise, they got laid along the way and two of them wound up with women wanting to stick around for the long haul. Which gets back to the point that you can have a significant appearance handicap and still do well socially. Compared to those guys you’re a giant.
What you lack is confidence. Which is sort of normal at your age. The cure is to talk to girls. Socialize with mixed groups of people. Cultivate hobbies and interests to make yourself an interesting person.
OK, then maybe you shouldn’t move to Manhattan…
Polls aren’t everything. Don’t panic. You will have sex. You will have girl friends. Odds are, you’ll get married and have kids because the majority of people do that regardless of height, ethnicity, family background, religion or lack of it, hair color, eye color, and about a bajillion other variables.
