You'll end up fucking, which may or may not cause a problem later.

>Is this a sound idea?
Eh...

>Is there something I should know going into this?
You two *are* going to fuck. Within the first 6 months, I'd wager.

>Any other related advice?
If you end up trying to turn it into a fwb arrangment, the only way I've found to keep jealousy at bay is to agree to secretly keep screwing even when dating other people. I've had three fwb in my life, and the two times that it ended when she started dating someone, I quickly got more interested in her and wanted to win her for myself. But when I had a fwb girl who agreed to secretly fool around even when we were both dating someone, it was the best situation I've ever been in. My whole life just went super smooth, week after week. Because I always had an outlet for screwing away excess stress.
