Red flag??? Pls help im scared

So I just met a guy a week ago through mutual friends and it’s been really sweet. He’s very affectionate and kind and says the sweetest things to me. And he’s clever. It’s like we’ve known each other for months. But here’s the thing. He’s been married before and got a divorce which is completely okay to me. But he’s told me that he cheated on his wife multiple times. He’s had sex with married women multiple times. And some weird details like anal sex etc... I know that’s not normal. And in my gut i feel like he’s a real asshole but he’s been nothing but nice to me. What do you think? Am i playing with fire here? Or am i just dumb? Or why is he telling me all this when i didn’t even ask once?????
