Friends with Benifits

So I've been broken up with my ex for about 6 months now. I don't want to be in a relationship right now cause I like being a free woman. But I want to be with someone physically. I'm kinda lonely and I've hooked up with this guy a few times and he has brought it up a few times. I'm kinda down for it but I don't really know what to think. Have any of you ladies out there had a fwb relationship. Any advice? Or precautions
