Do asexuals want kids?
Depends on the person. Asexual people can adopt, or if their partner is alright with it, carry through with asexual reproduction. (Like a sperm transplant.)
Some asexuals love sex, but aren't sexually attracted to anyone. So they can still have sex. There's nothing stopping them from having it.

Are all asexuals virgins?
A lot, but not all.
Like I said, some asexuals love sex.

How can asexuals get turned on if their not sexually attracted to anyone?
You don't have to be attracted to someone to get turned on.
Just because they lack sexual attraction doesn't mean that everything isn't working right in their bodies.
They can still get turned on.

How can they love someone when they're not attracted to them?
Romantic and sexual attraction is completely different.
Let's say you have a crush. You might fantasize with having sex with them.
We don't.

levels of asexuality vary, as aromatic stuff. If a person isn't romantically attracted to anyone (they don't want a relationship, and don't have crushes usually.)
And asexuals aren't sexually attracted to anyone. (They don't usually see a dick and say "das a nice dick. Mmmhm. Imma suck that.)

Asexuality is fake and anyone who's asexual is a failed human since they failed the basic human function to reproduce.
What about women who can't have kids?
Are they failed humans because they "failed" to reproduce?
No.
And neither are asexuals.

Do asexuals like to be touched?
Depends on the asexual.
An asexual relationship varys based on the person.
For me as an asexual it's mostly kisses and cuddles. ^^

I still don't get it...
That's ok! Asexuality can be a little hard to understand.

If anyone has any questions post them in the comments and I'll answer them to the best of my ability.

Btw these were all REAL questions/comments on a video that Buzzfeed posted about asexuality.
