Thanks for the replies everyone. For me, height is a huge deal (even at 5'10/a bit below at the end of the day). It's the main thing I focus on. If I see a guy who is better than me in some way (eg. better looks, better body, he's achieved more than I have) but he's shorter than me, I feel a weird sense of satisfaction/confidence/superiority/peace of mind. It's hard to explain. On the other hand, if a guy is worse than me in some obvious ways (eg. he's really out of shape, low achiever) but he's taller than me, I feel really insecure and like he has some sort of superiority/power over me. It's a really irrational thought process, I know. I also do weird things like search the height of celebrities (including female celebrities) on Google to see if I'm taller than them, and focus on people's heights in photos.
I feel quite submissive, almost still like a child around my dad and brother, like they have some sort of dominance/superiority over me. In my observations of height in every day situations, I notice taller guys are generally more self-assured and naturally exude an aura of dominance. Shorter guys generally seem more insecure/have a worse mental state and naturally submit to the dominance of taller guys. This disappears at about 6'2, when any extra height makes little difference.
Ultimately, I may be imagining this and I probably sound like a dck saying all this. But for my peace of mind and my own confidence/self-esteem, I would really like to be 2-3 inches taller. I'm almost certain it will improve my mental state.
That's all crap, dude, just go for it. Especially the last one, I mean wtf just say anything, who cares what they think?
The pain and possible complications are a genuine concern for me, and obviously I've got to say something to people.
