I don't think you're as alone as you think you are. At least 30% of the men I've come across have had some sort of shoulder/back hair and there may have been others who were waxing or lasering it off. Granted I live in NYC and this may change things a bit, but I don't think that 99% of men have hairless backs and shoulders!
Well, I think about less than 1% of guys have a hair problem on their shoulders and upper arms/back that are 20-30 years old. Look at pro athletes, college athletes, etc. Have you ever seen a NBA player with back hair or shoulder hair? I haven't. Do you ever see people at the gym with back hair and shoulder hair? I don't. Maybe they shave, I don't know...but if you can shave..then it's not a problem. Just shave. For the people that can't shave because of irritation or it's just too thick to shave...they are far and few between. Sure I have friends how have a small little patch of back hair, very small, not even noticeable. That doesn't count.
The last 3 months of my life have easily been the worst day of my life. Every single day of my life is worse than the one before it. I can't really take my shirt off with a girly, so I just quit talking to women I was interested in all together. It's not like I'm going to ever get close to them until I can clear up my hair problem. I have scabs, irritation everywhere, and then the hair still comes in. So I pretty much live in seclusion from females. I'm hoping I can get rid of this problem by next December because there is actually someone I like, but she lives 5 hours a way. Thank god...cuz then she can't come see me very often, and I can time when she comes and my problem.
I have a feeling it's going to be about 2 more years of this. I'm almost 3 months along and I haven't even gotten to a full clearance yet of the entire area. But it should go quicker from here on out. Getting large body electrolysis feels like being in a prison.
