I mean, when Gale asked me if I want to hang out, I said yes, not knowing that he wants to have sex with me. When I realized what's going on and backed out, and the game almost scolded me for "ruining a magic moment".
I thought I had just a friendly chat with Wyll about dancing. Next times he offers to dance with me. I say "thanks bro, but no". Wyll looks like the most heartbroken person in the universe.
Gale only has a sex scene in act 2. For that, you have to initiate the act 1 weave scene, when the narrator talks about the air feeling intimate and you're given the option to just think about having a friendly dinner with Gale. His sex scene never triggers if you click on the friend options.
With Wyll you only get the "dating with Wyll" flag if you were flirting with him at the tiefling/goblin party.
