I just see all these famous guys with straight hairlines and that all the girls go for guys with a straight hairline... I'm just really self conscious about my hairline and seeing guys with straight hairlines makes me even more stressed out and depressed. I can't even have a short hairstlye because of my insecurity...
I understand your insecurity, but I assure you that it's just a false impression coming from your own obsession if your hairline. A lot of non balding men have non straight hairlines and I really don't think that women prefer the straight ones. Look at the V shaped hairlined of the likes of Chris Hemsworth, one of the most desired dudes in these days.
Also, I wouldn't shave the center of your hairline, that would look weird. You don't need the straight look Zach, believe me, you are fine, man.
