My experience has been it doesn’t matter unless one party thinks it matters.
I hung out with a guy eight years younger but we checked every box on compatibility, humor- had a really good time together.
The age gap prevented him from moving to more serious. At my then age of 35 knew it’s rare to find a connection like we we had but he had not experienced enough to know that. We are still friends and he’s 32 now and still single and I like to think he has occasional moments of regret, haha.
This is of course more common when the female is older so if he’s hot, funny and
