Help! Situational question

Hey guys, so I'm currently on day 20 of my nofap journey. Things have been going much better for me thus far, and really have no desire to watch porn. Quitting porn has been easy for me thus far, the only difficult part has been no MO. Anyways, I've been doing hardmode, and I've been extremely horny but able to hold off. So, the problem I'm having is that I've been chatting up this girl who wants to go out for some drinks tonight. I'm fairly certain she wants to hook up with me. My dilemma is twofold.

1. If I hookup with her where does that leave me in my rebooting process?

2. If I hookup with her having not MO'd in 20 days, I feel like I'll experience some pretty serious PE.

Should I just say fuck it and forget about it? I'm fairly new here so I'm unsure if people still have sex while rebooting and if that's detrimental to them etc. Have any of you guys been in a similar situation? Please share your thoughts. Thanks in advance!
