Ok so I am currently 24 years of age, and I do not have a girl/boy/animal (shudder) friend. I am just fine with that, but as of recently I have begun to wonder if something was a little tweaked in my head? I am not sexually attracted to anything at all. And I'm 24. And I'm a male human being.
Notice I said "sexually" attracted. I still love people, I just don't involve romance or sex.
But as said before, as long as you're happy, why not?
You should get checked by a doctor just in case, too. A lack of sexual desire and libido could be explained by other causes.
Being asexual means you are free from all the burdens that a mans cock puts him through.
Count your blessings.
