I made my bsf hate ragebaiting me by getting turned on

So me and my bsf (both men) screw with each other a lot. When we first met, I was very transparent with the fact that I was gay. He understood this and didnt care.

One of his favorite ways of ragebaiting is calling people good boy/girl whenever he pleases. Naturally, I eventually become his target. He called me a good boy every day for no reason.

What i didnt feel the need to tell him when we met was that I am a masochist, and live for praise like a bitch. One day, unprovoked as hell, he asks me to do something. I do it and he says it but he says it with MEANING And suddenly im rock hard. I cover myself and he notices. After a few days, he asks and I reluctantly explain (as vaguely as possible) and ever since, he avoids saying it around me.

It's not that he's uncomfortable, its more so that I think he's questioning his sexuality
