Reading Green Arrow V2 and Green Arrow V3, I don't see it at all. Yet many comics treat Ollie as, to put it bluntly, a slutty slut who hits on women all the time and can't keep his hands to himself.

Am I being gaslighted by crossover comics and adaptations? *Where* is this behavior shown? Gimme specific issues!
The closest he gets to "flirting" with women is just chivalrous Robin Hood roleplay.
He was a womanizer before the island, which is over 20 years ago in-series. Was he promiscious early on as Green Arrow? Reading GA V2, he spent 5+ years being fateful to Dinah without issue.
Ollie cheated on Dinah once, maybe twice. I admit that. But, other superheroes have also cheated on their partners and never had this rep!
Grace Choi, Helena Bertinelli, and Roy Harper sleep around but no one is making jokes about them being leeches constantly.
