I get what you mean, but you almost make it sound like hitting up craigslist for prostitutes. You still have to hit people up, meet up with them and make everything happen. Aside from minor things it’s not particularly different from trying to fuck a girl you know or some random girl in a nightclub.
The longer I do this sort of thing and the better it gets the less it feels like I’m doing something other than being completely normal, and as a result I’m less and less bothered. Sometimes I feel like going for a night out and taking a girl home at half 3, sometimes I want to meet up with a new girl at a bar round the corner from my flat and do the same. And if I can arrange the latter through an app on my phone on the bus I don’t see anything wrong with that.
