You just haven't met the right person yet
So... celibate?
How do you know if you've never tried?
Get your hormones checked.
But sex is human nature!
That's not what "asexual" means.
You just haven't been with me yet.
That's so noble, saving yourself.
You're just shy/afraid of getting close to people.
You're repressed, get some therapy.
So you're super religious?
You must have had a bad experience.
You can't get a date.
You'd be into *hypothetical situation*
You think you're better than us.
You just have a low sex drive.
But you masturbate?
That's just sad.
It's a cover for something else/you're really...
You're just confused.
That's a shame.
You must be sheltered/innocent.
Isn't that lonely?
You just don't want to risk STDS.
Prude.
