After reading your responses, I think you’re basically asking how to casually date friends, right? For casual dating/sex, stay away from friends. It can ruin the friendship or even the entire circle of friends. There’s always the “friends with benefits” thing, but even that often ends badly. For casual dating, stick with strangers. Aren’t there a ton of apps for that sort of thing?
