I have in the past, when I lived in a big city. Gone to a club, met a hot guy, took him home. Not necessarily with the intention of it being a one nighter, but if you take a guy home on the first night, you have to keep in mind that's probably all it'll be. I'd had exceptions where the guy called me and we actually hung out a few times after, but not always, and that's okay. Now that I'm living back in my home town, it's a lot smaller than the city I was in previously, so I wouldn't do that (if I was single), because too many people talk and everyone knows everyone. I don't want to be portrayed a certain way, so I avoid actions that will portray me that way. I think as long as your being safe and not hurting anyone in the process, it's okay. If both parties are single and consenting and you use protection, then I don't see the harm.
May the wind always be at your back and the sun upon your face. And may the winds of destiny carry you aloft to dance with the stars
