I cringed at the use of "make love." Nobody says that lol.
Of course they don't.
But in all seriousness, the point he is trying to make is at least arguable. He's essentially preaching an extreme form of "nofap" for your eyes. If you aren't getting any, don't use her as free porn.
And what's the likelihood you will get some? She'd have to be interested, not be an AW to you, be available, etc.
Realistically, if there are attractive women around, you will always notice, even if it just via your peripheral vision. But not gawking at them (or even attempting to check them out) unless you plan to approach doesn't sound like a bad idea. Even the PUAs warned about looking at a chick too many times (or too long) before approaching because it can creep her out.
Sometimes being in a girl's vicinity can creep her out. Not every guy is Chad or Tyrone or Enrique or Hiroshi etc. But how often do women approach you for alpha purposes? Not beta purposes i.e. taking their pic, liking their pics, complimenting, BF issues, etc.?
Maybe this could turn into some hardcore "ignoring-whoring" or "ignore game" if done before you approach.
What good does it do if she's not checking you out, and you aren't either? Sure you're not a weak pushover giving out free attention, but you're not advancing anywhere with the girl either. Have fun with your right hand and that baby lotion, you'll need it!
I think there may be some potential here.
