So I've recently acquired a FWB in my circle of friends (I know.. I know... don't shit where you eat... but she's hot.)

I was just wondering what tips do you guys have so we can continue a friend ship and continue sex without getting anything complicated.

How often should we talk, how often should we fuck, talking/cuddling in bed after sex, kissing when leaving, etc.

Im not sure about a lot of stuff like that, so any tips to make this last as long as we can would be helpful.
