Interesting, will add some of my thoughts below.
Femdom - for me the biggest appeal is the intimacy of giving up control along with the anticipation of the devious, creative unknown of what will happen next. Letting that other person able to use me for her whims is just so sexy. Also I love the challenge of it, being pushed to perform better, edge more and just taken to places it's much harder to take myself if I am in control. Last aspect is with a partner I truly appreciate, the aspect of devotion to them, showing it through that given up control. And last, it's awesome to feel like a good and cherished slut sometimes LOL.
For specific actions and such - a lot of it just comes down to what I'm really into in general. Femdom is just who's in control more than a specific kink to me. (Edging, orgasm control, ballbusting…etc).
Humiliation - not really my thing on its own, actually may be a turn off if done for the sake of it. Where it's hot is because the domme enjoys it. When she's putting her good slut on display, or reminding me how I worship her. Playful, fun, teasing humiliation is also really fun. I don't really think of many acts or positions as inherently humiliating, context matters so much. Example - walked through a sex club naked on a leash to be shown off as a matter of pride is way different than the same situation to be laughed at and ridiculed. One is hot for me, second is very much not.
Bondage - sexy as hell. And for basically the same reasons, it's a giving over of control. It can also be just very visually appealing, I love tying a woman into a rope harness with strategic knots in places…or so everything is accessible for fun. My main theme, context matters. Just being tied up with no real other reason isn't going to get me going, the way being tied up for a purpose will. Also mental bondage ("don't move") is very sexy because it's completely willing submission.
Cumplay - Giving it's just so damn sexy. Visually appealing for sure, especially on face and breasts. There's an extra appeal when she just wants it and is looking up at me right before I cum all over her. It's so hot when she's eager for it, licking it up off herself afterwards…just mmm. It can of course be one more bit of control too.
Receiving - this is all about control and devotion. I don't think I look particularly sexy splattered in cum, but I'm not into guys so I'm probably a bad judge there lol. But in that femdom role being made to cum on myself or lick it off her or something is one more lever of control and devotion.
Making a girl cum all over me or squirt on me is super sexy. I love the feeling of making her feel so incredible and having that physically hit me/tasting it.
Excessive cumplay like freezing it to have on hand or snowballing has never done much for me.
