No one will ever give you a clear answer, because there are just too many catalysts that can cause someone to want to get limb lengthening. Even beyond just dating, or respect from other men.
Think about every time you feel short around family, or when a younger family member grew significantly taller than you (far worse if they're the opposite sxx). Or think about seeing your ex-girlfriend get swept up by some 6'2 dude. Or think about the little anxiety you get before meeting someone for the first time, not knowing how tall they are. Not just blind dates, but job interviews, prospective clients. Think about seeing yourself in photos, (ugh, photos with girls in heels) and seeing yourself as the shortest in the entire group, shorter than most girls. Think about having great ideas and aspirations, but knowing that people will take you less seriously in every aspect of life because of how short you are.
At that point, it's not just about being confident. I'm a confident person. I'm confident in my ability to do things and my tenacity to get everything I want. But you can't be confident about being short, there's just nothing redeemable about it. You just can't be confident about the things that affect you, for the most part, in an entirely negatively, and saying anything otherwise is major coping.
