I agree with ForcedPuberty......I think that women are attracted to certain biological traits but most of all to confidence. What is confidence??? It's like trying to describe "spirit" or "soul"...no clear definition. IMO, confidence comes more naturally to taller men because they grow up not being picked on, not being ridiculed when they speak their minds(even if what is said is stupid). Also, the way a tall person carries themselves is different because most people will be at eye level or bellow and therefore a tall person will have a relaxed eye gaze(bedroom eyes), and usually not afraid to make eye contact and maintain it very comfortably in a non- threatening way.
I recently used "beta blockers"(they block the fight or flight receptors in the brain) because I am terrified of doing presentations for school in front of the class and they worked as anticipated. What I didn't expect was the way people were reacting to me outside of class and in the street. Suddenly people were very receptive to what I had to say, treated me with smiles and seem to go out of their way to help me. I thought it was a coincidence, but it seem to have happened every time the drug was in my system. It was like it erased most of my inhibitions and allowed me to be comfortable with who I am. The only other times I am able to feel that way is when I drink alcohol, because I become a laid back dude. The only bad part of being drunk is that my judgment suffers and sometimes gets me in trouble. Meanwhile, with the previous drug my judgment is razor sharp and no inhibitions.
The point of all of this is that when you grow up as a short person, you are likely to suffer from a constant feeling of threat, trying to over-compensate by proving superior knowledge/intelligence, exaggerated body building, and worst of all displaying ridiculous signs of having wealth(flashy expensive brand name clothing that looks tacky, driving cars that are clearly out of price range, etc., etc.) This being said, not only short people do this. Everyone is guilty of some form of trying to compensate for our shortcomings. The problem is when it becomes too obvious and it has the opposite intended effect. Women are repelled by this, ffsk men are repelled by this. We get angry and blame others for being prejudice, racist, superficial, when in reality it is us who cause the problem by constantly seeking validation.
Now, to answer the question of "Does getting leg lengthening make you a wimp?" Yes it does if you are going to become taller just to constantly bring up the fact that other people are shorter than you, make remarks and observations constantly about how society views height as a desirable genetic trait, etc. People will see right through that and all your sacrifice will be in vain.
The journey of doing LL becomes a success when it is able to "surgically" remove your mental insecurities of being short. Otherwise being 7 feet tall will not solve your problems if you continue to overcompensate and continue to compare yourself to everyone around you. Understanding how your mind really works is the most important step prior to making a big decision.
PS. I don't endorse relying on any drugs to enhance one's self. There are always potential dangerous side effects. I only mentioned the above because it made me witness of how my own paranoid behavior makes people treat me less favorably.
