LOL, not everyone. I could say I did it more for men than for women. I just don't like being worse than average in anything. I would do more lengthening to reach 1.80 m but it would be unwise. Being taller is better aesthethically, longer reach and more weight (fight advantage), people naturally see you as more dominant, etc. Unfortunately only some of these advantages are gained after LL. I think women like taller men, the taller the better until you reach 1.90 m depending on the girl.
From 1.80 to 1.90 a man's height is excellent. Some women tend to prefer men closer to the first while some others men closer to the second border.
Between these heights, face and body (muscles, symmetry etc) play the biggest role as whose man women will find more attractive and not height per se.
Personally, I was more closed to myself before LL and I was afraid more of rejection. That said, 2 of my 3 best looking gf's were with me before LL and the third that was with her after LL said sometimes that I would have been better if I was taller, something the girls before LL never mentioned.
Also, many women told me that with some extra height I would have been perfect so these women would have easily rejected me before LL.
So yes, LL helps a lot in dating but still there are some borders that defines the success you have.
If you are still less than 5.7 after LL then the difference will be minimal, if you reach a height between 5.8 and 5.10 you'd see a good difference and if you become more than 5.11 then the difference would be huge.
So what matters more is your final height.
I was 1.68 before LL and 1.75,5 after, both morning heights. At evening I am 2cm less.
