If two antisocial people go on a date how much awkward silence will be present?

You're assuming that all antisocial people carry themselves alike but this isn't true.

I knew someone that was rabidly antisocial and everybody thinks she's the sweetest person they ever met.

As for me. I make no secret of the fact that I think most people are not worth glancing at my watch if they ask me for the time.

It won't be "awkward" ...it would be welcome. Lol

the more the better. 😹 kinky sexual tension followed by pure animal instinct.

If you’re both introverts, is it really awkward..?

they'd probably go to the woods camping and all

Depends on each person. If they are social enough to arrange a date then perhaps theyvwill be fine
