An other option would be nice.
I have never properly dated a person. I've usually only slept with someone before I dated them. Not the best way to do things. Happened with my current girlfriend, though, and she and I have been together for 8 months. Usually I'm only dating someone for a few weeks or months after sleeping with them.
My gf and I slept together a few times when she was in town visiting a mutual friend for her birthday and we really didn't plan on speaking to each other again. But I started to like her and I kind of had a feeling there might be more on her part, too, so I started to talk to her friendly-like and it just escalated from there.
Anyway, I really don't have a problem with sleeping with someone up front, but like I said, I've never properly dated someone or courted anyone before having sex.
