Nowadays I might trust you more. It's less about the history of it and more about the active practice of doing stuff like that. Like a frat boy that gets drunk and screws different girls every night? I wouldn't trust him. For me someone saying "Yeah I like to have a lot of sex with random people" is right up there with saying "Yeah, I drink a bottle of vodka every night." or "Man, heroin is pretty great". It's a red flag, a warning that person is gonna put themselves and their desires ahead of basically anything else. Which isn't great if you're depending on them for something.

I don't have a moral obligation to it; I've just found that trusting people like that to be reliable in any way is generally a poor choice.
