Credentials: am always somewhere between friendly and flirty, and love giving (and getting) good compliments.
Testimonial: Last week I explained this to a nice woman who said she didn't know how to flirt. A couple days later, she texted me that she tried it at a party over the weekend and ended up having sex with someone. (I can't tell you that it had anything to do with my advice, or that your experience will be similar, but it's a thing that happened)
