Rose yeah that is an option.
I have done it before in the past, usually if I'd been stood up and didn't want my shaved legs and various other efforts to go to waste... and yes you can easily pick someone out and have them turn up within a couple of hours.
It's not currently what I want though, and it's not for everyone. Haha.
I like a date of some kind first because I think it's better with a bit of build up and flirting. And then to have repeat performances when each other have free time, rather than never seeing them again.
Sex with a connection with that person is way better, and the 2nd, 3rd, 4th etc times onwards tend to get better as you get more comfortable with each other and know all the likes and all that.
Although when I used it for my Glasgow trip that was the first time I'd used it with the specific intent of never seeing the person again.
Even in the past when I've used it for an urgent meet that night, I still intended to see them again until they turned out to be rubbish in bed then I got rid asap and never bothered with them again
