Plus, approaching a broad in a "creepy" manner is only one scenario he mentioned. He also mentioned the scenario of approaching the "wrong" broad (I take that to mean a taken broad). Even a neurotypical isn't going to know off the top of his head if a broad at a party is taken (unless he knows her...or unless he sees her and a boyfriend together at the party)
The thing about making a solid approach is to
not directly ask a woman for the horizontal mambo.
I know that runs counter to the DJs here who think direct approaches work better than indirect, but I tend to do neither. How I interact with a woman depends on the interaction. Socially calibrated men don't just start talking about sex and intimacy, they wait to escalate with sex talk until the woman shows clear signs she's sexually interested.
When you are a sexual person, women can 'smell' it on you and they already figure why you are talking to them. Experienced versatile lovers are rare and women will instantly know when they're in their presence. It shows most often in what is often called 'confidence', these people are comfortable in their skin, move leisurely, radiate calmness and alert detached observation.
One of the reasons I don't get 'rejected' is because I don't show my cards until she shows hers. I won't escalate the conversation sexually before she does. When she shows sexual interest, I will tease her with innuendo, but I'm not eager to engage, so they have to put some effort into getting my attention and (sexual) validation.
So when a woman falters in conversation and I lose sexual interest in her, I just don't escalate, even if she does. And if she does I can signal non-interest without 'rejecting' her directly. And if she doesn't escalate, she's either not into me and/or already taken with someone she doesn't want to cheat on.
So, I don't have to know whether the woman I interact with is seriously involved with another man. Either she's interested and escalate by sending me signals that I can escalate too, or she isn't interested for whatever reason.
