For the scars I would say I had a horrific dirtbike accident as a kid, but that's just my silly excuse. As for women, LL is in no reason to be for the opposite gender. My girlfriend did break up with me when she grew taller than me in high school, but that's when I didn't have much to offer. Security and affection are the best traits to offer a woman, and can guarantee you a partner regardless of looks or height. I've always hated swimming ever since I quit my swim team ten years ago, so wearing a bathing suit is not a problem for me. Although, this is about you and I will get to that:
Scientific studies have been done on women, and many have stated as long as he's tall, they could care less about looks.... so it can be a plus after LL, but you have to be a man of character.
Sure, your proportions might be "weird," but as for anyone in this forum, we couldn't point out too many flaws until we went into deeper detail on measurements after we took a tour on CLL. I am doubtful that the average person on a daily basis would think "Wow, that guy's arms are really pathetic." That's your arms, allowing many to accept what you have and embracing it is a powerful trait that must be expressed.
People are going to point out flaws, and if they do, just don't care one bit; them being judgmental about others before judging themselves only puts them in weaker categories. Apotheosis: a tall, handsome man only beats down on us. However, we all know who he is inside, what he emits, and we can pick him out quite easily, demoting his alpha character into that pool of beta.
Before and after LL, put up a smile and balance your character. Be yielding, but express aggression to your environment. Once you reach that, people would have no choice but to respect you. The words you are reading right now are in your head, as time progresses through experiences, it changes how you process what I am typing, but it's not blatant nor complicated, it's just simple but difficult.
But the best I can say for your situation is build more muscular mass and see how that would turn out in terms of LL worthy proportions.
