Partner [m] finding a whole new side of himself with me [f]

Back story* We’ve been together for fifteen years. Fucked like rabbits at the start. Had a kid, went on birth control. I thought it was the kid + some ppd that basically destroyed my libido. Turns out it was entirely the bc. Since going off it my drive has gone through the roof. I’ve always had bdsm fantasies, but due to being a complete wuss, plus having anxiety have taken fifteen years to articulate these to my partner (Yeah, I know I’m ridiculous). Since telling him though, he’s gone from super vanilla, to really starting to move into a very dominant role (Yes!) End back story*

We were fooling around a bit last night. Nothing that I thought would lead to anything, just kisses and cuddles. Until he grabbed my hair and growled, “You’ll suck my cock now.” Woof, instantly wet. I immediately get to it and he’s swapping between pushing my head down and holding until I literally have to tap out (I’m more than fine with this) and teasing me with his fingers. And I mean teasing. Bastard. He’d just brush my ass hole, put a bit of pressure, then move on. Same with my clit and pussy. Just light touches, then nope. So I’m going mildly insane by this point.
