Pretty much the title

Does it actually help or not really?

On one hand, I have seen some who say for many reasons that it does

  • "He might just pump and dump me, so this vets against that"
  • "When sex is in the equation, it can cause attachment too quickly before really getting to know each other"
  • "Their reaction to being made to wait shows their mindset and can help you gauge your compatibility"

For some I can say I've seen their reasons why it doesn't help:

  • "Waiting won't even stop a guy from pumping and dumping unless it's for a ridiculous amount of time"
  • "If she's making you wait, she easily could be stringing you along even though she's not attracted to you
  • "If we have sex quickly after knowing each other, we establish compatibility early on"

Who do you agree with more? If you agree with the people who say yes, then how long would you personally wait/make them wait and why?
