You can't be 6'3 - 6'4 cornball loser and expect women to like you just off of your height, yes, it helps, tremendously at that, but it needs to be complimented in order to function as a magnet, if a woman was to choose between the best versions of a 5'6 guy and a 6'4 one, you can already assume which one is the right answer. Work on your alternative abilities, skills, education, knowledge, fitness etc, you already have the frame, which is a huge potential, don't let it go to waste. Everyone can gain muscle, nobody can gain height, or at least not as easily.
P.S. I didn't assume you're a cornball loser, I was just giving an example, judging by your comments. I'm 6'4 myself and I had to work for it, but compared to what you get in return, the work that needs to be put in is ridiculously small.
