So into this now (F22)

So my boyfriend got me into this fetish about a year ago . How I discovered he had this was I was going to go in the shower when I came home from the gym and he was in so he hopped out when I came in and started to take my clothes off when he teasingly told me that “no matter how much I hit the gym I’m still a pussy” he was sitting on the closed toilet drying his hair and I put my foot straight on his chest and pushed him back I was wearing black Nike socks and tights still but was took my shirt off so I had a compression bra on. I said “ Your the pussy who begs on his knees for me to put your dick in my mouth all the time “ He starts laughing and agreeing and I just straight up moved my foot straight to his dick and balls and pressed a little to just tease him and he got instantly hard I started grinning my foot under his dick and laughing and he looked super embarrassed.

I didn’t think anything of it because I didn’t know it was a fetish honestly I’ve hit so many guys in the balls I would never think of that in a sexual way he came up to me and explained everything and how he was embarrassed to even tell me and wanted to just ignore it for the rest of our relationship. I explained to him that it’s not weird at all and I truly understand what he finds hot about it about so now about a year of doing it I was very hesitant with him at first because I didn’t want to hurt him but the more comfortable I got the less he ask for me to hit him lol. But now the thing is I’ve gotten very comfortable doing it that I’ve out of instinct hit other guys that aren’t him I’m certain scenarios. It’s always friends of ours and it’s never sexual just gotten so use to doing it if we are ever joking around and he says something mean or just playing . I’m more than sure he finds it hot. Just doesn’t say anything.
