What I will say is that, having successfully done LL and ending my height neurosis, I seem to notice a lot more couples where the man is shorter than his woman, OR just generally short men who are very successful in life. I think before LL, I had so much pain due to my own height that I was sort of blind to all these things. Or maybe I was just seeing what I wanted to see.
Unfortunately, most dating nowadays happens online, and short men (below 5'7"/5'8" especially) are going to have a harder time. Many woman would totally be fine with shorter guys, but in my experience, thanks to social media/online dating, no one seems to talk to each other in real life anymore, so we all resort to online dating. This, in turn, makes women extra picky, and many have straight up told me that height is the first thing they'll use to quickly narrow down all their options.
I never wanted or needed to be the tallest guy around, I just didn't want to be the shortest. Doing this surgery has accomplished that for me. I almost never feel short anymore, and I rarely find women much taller than me, even in heels. And I definitely feel much more attractive from having done LL (I always had the facial aesthetics, but being 166cm just negated that entirely). My proportions aren't perfect, but no one has ever really commented on them except for one guy at my gym (who was watching me deadlift and squat) noticed my femurs were on the long side. But even women who've seen me nked haven't commented, and I think having muscular legs helps camouflage the proportions a bit.
I very rarely get knee pain anymore, and when I do, it's very manageable. Only seem to get it when I run, so I don't run very often (I get my cardio from intense flow yoga, stairmaster, elliptical, etc.). And sometimes when I travel in airplanes, I get right leg pain. Dr. R believes removing the nails will help, so I'm doing that this fall. A bit nervous about that and not keen on having new scars, but whatever, I will deal.
Overall, I'm happy I did LL.
