As someone who has been between 5'5" - 5'11" via a combination of shoe lifts and LL surgery, I can vouch for the idea that being taller even by 2 inches can make a "huge difference in gaining attention from females and respect from other guys". But also as someone who's been through the LL process and paid $100k for his 8 cm, I can also tell you that it's less worth it going from 5'9" to 5'11" and probably even more so going from 5'10" to 6' compared to going from 5'6" to 5'9". That's what these shorter guys are saying and since I have experience in those height ranges, I can tell you that it's true.
I've been through all the mental torture and stuff and even have the opportunity to go through the whole process again on my tibias to get to 6'. And even though I have almost unlimited money and don't have to work, I wouldn't do it again. So while I'm not you and aren't in the same environment as you, I personally think that you will regret doing the surgery at your height. As you already said, you're healthy and have money and have a good relationship with a very cute girl. I believe it, because at our height, it is still easy to get girls. Would it be easier to get girls at 6'? Possibly. But is it really worth it? No. No girl or guy's respect is worth putting yourself through all this torture and financial loss. I don't mean no disrespect, but it's actually crazy or stupid that you'd be willing to go through all this just to impress other people. This is where I'd agree with Alu's opinion that therapy would probably help more than LL. Because you might end up replacing sadness about your height with sadness about how regretful you are for doing this surgery and destroying your perfectly working legs because some girl doesn't think you're tall enough for her.
It tends to be younger guys like early 20s and teenagers who have this train of logic/thought. I'm not putting you down based on your age, but you might be letting your dck/shallowness do the thinking for you, and that's bad. At around that age, you haven't accomplished much and people tend to base their opinions on others by superficial features like their height. But as you get older, you'll realize that it's better to get respect from the things you do and how much money you have rather than respect for your height. And as someone who had a lot of respect at even 5'6", I can tell you that nothing is really holding you back from what you're trying to accomplish at 5'10". Use the 120k to get yourself a nice car or nicer house. You'd get way more respect from people for that than just being 2" taller.
Again, I'm not trying to put you down, but instead trying to warn you that you probably would regret doing this surgery. The returns are so small at your height that you're better off just wearing shoe lifts.
He hit it right on the dot. I have just turned 22 and have never had problems with girls. While yes I'm limited to girls 5'9 and below, that counts for most girls. Being called "short" or "i thought you would be taller" is only very rare and usually from girls who are lower quality and expect me to be 6'0 just because of my looks (6/10 PSL wise, 7 irl). I'm from the looksmax forum and I really was drooling about this procedure, especially with the safety and recovery that comes with Dr. Paley and only 5cm.
And @DoingItForMe summarized exactly what I have been looking for and experiencing lately. I have a 6'0 friend that doesn't even look taller than me and I look almost "taller" just because of my skinny and lean build. He's denser and heavy framed so he appears my height. I've asked many people, girls and guys tall and short, and they all say I pass as 6'0 (with shoes) and a 6'8 friend told me himself that I definitely wouldn't need to go through a surgery and I am fine with my current height.
My only reason of going on this forum is because I knew about it, and one day I was the SHORTEST GUY in a bathroom. It was insane, and I couldn't believe it. So yeah, I searched about it and was really into it for a bit, down to spend the $. - It would 100% benefit me more if I invested it back into my personal life, with a house or savings, and I know that it would benefit me in the long run to save these funds.
I want to thank @DoingItForMe for solidifying my decision to
not get LL and be comfortable with my height.
