Welcome I'm 23 too and was tired of the receding hairline also!
Do it, trust me you won't look back!
I hope so! I'll post before and after pics...most people think I'm crazy cuz I have a decent amount of hair but I grew it out a bit more so it kind of hides my hairline...at least it was haha and the fact that I shave my "widows peak" which isn't really a widows peak just part of my receiding hairline..I'm half black half white so I can't really grow "long" hair that would do a comb over ha
I have a decent amount of hair. I am not balding, but I shave my head anyway. You are not crazy. Guys with a full head of hair do choose to be bald by choice. It's an OK decision. It's an even better decision if you are balding a little bit or a lot.
I love being bald. Hope you do too.
