Cool, I get it.
I'm just never sure when is the right time to start throwing in these reveals. The way my brain works right now is that I have to keep it cool initially, assume I do have to build up some value to her through the convo, qualify, and look out for IOIs. Is this correct? Wrong?
That's not really the right way to look at it. You're not building up to this "big reveal" moment where you tell her you think she is beautiful and she then knows you like her sexually.
At the beginning of your date you'll do all the normal stuff: DHV, qualify, push/pull, etc. Throughout that time you are conveying that she likes your stories and thinks you're cool. You do this by laughing at your own stories or laughing along with her when she laughs and you basically play everything up for effect. You can say "Wow, you're a lot of fun!" Instill this sense of you two having a good time together and you being this cool dude that she likes.
However, you will ultimately be aiming to escalate shortly thereafter. Once you built rapport, start physically escalating. The ioi's are not something you need to look for. If she gives them, great, but you'll ASSUME you have the greenlight anyway. If you notice an iod, then recalibrate. But the point is you can just assume attraction and escalate and not worry about ioi's or iod's as you might not get either by the time you plant a kiss on her and start making out.
