I'm 5'10 and I admit that I don't need anymore height. I've had no trouble with women at this height besides normal rejection that all men experience. I don't attribute those to height. And I've had lots of success that I don't attribute to height as well, so it's safe to say that at 5'10 height doesn't affect me socially. But not everyone wants LL for social benefits:
But I feel that I would really look much, much better with two more inches on the legs. I have broader shoulders, bigger fists, larger bone structure than my 6'2 father and my 6'1 cousins, and around the same upper body as them. I just look a bit stumpy sometimes, even though I'm in great shape. I think maybe my puberty was too early so I ended up this way, because this kind of build is typical of people who had precocious puberty. But my dad had an even earlier (and almost abnormally early) puberty and hit 6'2 fully developed by age 13. His brothers had more normal puberties and ended up significantly taller than he is. My brother is similarly built to me but has more proportional legs compared to his upper body and slightly smaller bone structure.
There's also a certain discontent that comes with being one of the shortest men in one's extended family. Obviously it isn't going to make me or most other people miserable, and somebody has to have that position, but I'm personally sick of feeling that way for years and being the noticeably shorter one in all the pictures etc.
Two inches on the legs just looks so aesthetic as well.
I only want 5CM, 6 if all goes perfectly, but I admit that I by NO means need it. But LL is something that's VERY VERY VERY hard to forget or push permanently out of your mind once you've found out about it.
