Becoming FWB

I met this guy on tinder almost a year ago, and literally our conversations were so boring like it was not going anywhere. But we always remained cool and had a each other on social media. Monday, he hits me up on Facebook just having conversations and I already had a feeling he wants something. So we talked about what we are looking for and basically he doesn’t want anything serious because how busy he is with his career I guess

So he asked if I would be interested and I was like no in the beginning but then I told him my ground rules and somethings about me sexually he should know before having sex. He’s good with everything and he also told me his turn ons and that he’s so weird he doesn’t gain feelings?

I wanted to say sure “OK” but I guess we’re becoming friends with benefits. So is there any tips you guys have? From what I hear it can be complicated.
