Signs a male is addicted to porn early on

Someone recently posted that they waited to have sex bc of personal reasons and eventually found out he had issues related to porn. Essentially stated she regretted waiting to have sex bc it would have saved her time.

I’m mentioning this because I was the opposite with my ex partner, we had sex on our first date and it took 1 year to clue in that he had a porn problem.

For those that have been in a relationship with a man with PA what are the early on signs or patterns you’ve noticed?

Asking so I avoid and look out for them in the future
