Advice...

So my FWB and I have been dealing with each other for almost a year now. We've known each other previously and things are great as we see each other when we can. I'm just curious as he's been going down on me almost every time we hook up, and he will go down on me, give me the d*^€, and then go back down on me.

He's also interested in hanging out/spending more time together outside of just hooking up. For those that have been in a situation like this, or who know men in general...does he have feelings for me?
