I like to think about "Questions nobody wants honest answers to." So here is one, and you can perform an experiment: Go to some kind of forum, maybe Reddit or Quora or Metafilter (just kidding don't do Metafilter unless you are a masochist) and ask the question, "Where can I, as a single hetero male, go to approach women?"

My prediction is that you'll get some "OMG DON'T!" responses, and a lot of "where NOT to," which does not answer the actual question. For there to be relationships and/or sex, somebody has to make the approach, and that means a location in spacetime, a where and a when.

The workplace, previously one of the largest places where this occurred, has been ruled out, which is a bit troublesome given that most people spend a rather large percentage of their time there. Oh, we kinda stopped going to church, so that is out. Bowling alone ... uh ... then maybe you ask about the library and someone will say "I'm just there to study" or a bar and it becomes "I'm just there to hang out with my friends." Always in the negative.

Where are these approaches to take place? Have we collectively decided to hand this over to match.com, Tinder, Grindr, whatever, and now it is all online?

If relationships and sex were food and water, there's chunk of people who would expect you to politely starve to death and not make a lot of noise about it.
