Well I'm 24 and I don't grow hair on my chest, I don't know why, just never have. I don't have any on my back either thank God. I shave all my pubic hair and have since 18 because I think it looks and it def feels better. It sucks to shave twice a week, but it's worth it. Truth is, if I did stuff with a girl and she didn't like that I am bald down there, well that's her loss. I do it for me, the benefits that girls like it is a bonus, and those who don't like it just don't get it. Those who think it's gay, I know tons of gay guys that don't shave bald. I don't shave my legs, but I do trim my armpit hair just by using a 1/4'' on my buzzer once a week.
