20 y/o, 6'1, been lifting for a few years, got a good job, am in good shape, etc... Biggest problem: I have legitimate autism, i've been seeing a shrink to help learn social skills

Story: Yesterday was the third time i've seen this one girl at a party over the past two weeks (6/10) I've chatted with her, kinda hit it off, in hindsight she's been giving me googly eyes and shit The first night i met asked me for my number (I gave her a fake, cus why not right? Autism) At any rate...

Last night at the party, same thing i chat her up a bit. Right before she leaves she wants to "Talk to me" She says something along the lines that i'm an asshole for not picking up my phone, i finessed it by saying i was drunk and punched a wrong number. She pretty much said she thought i was cute, and she wants to get lunch or dinner today (23 July).

This girl i think is a bit of a skank, but tbh idk, i'm just tryna smash

But that's where my problem begins. Idk what to do and i'm worried about being humiliated for being a 20 y/o virgin when she inevitably discovers i can't kiss or fuck for shit.

What do? I'm a nervous wreck

I know this is what i've been wanting, and this is my chance to fix my biggest perceived insecurity, but it's the how that's bothering me
