Trab is right Udeluz, you're gonna have to do it if you want to do a show...or you can keep the hair and compete....that would be weird.
As for me and hair, I don't know if this is a coincidence or not, but once I started "using" my body hair got even worse...I never had any back hair until I jumped on AAS. I used to shave it myself when it wasn't too bad...that was not the easiest thing to do but I did figure something out...but it's gotten worse over the past couple years or so. Luckily for me though, one of my younger sisters is an astitician, and she can take care of it for me. I've shaved and waxed and waxing hurts like a bitch, but it last a good while. Next step, I'm going to get it lasered her in a few wks, free of charge...hopefully a few sessions of that will take care of it permanently.
Body hair sucks!
