Female led relationships discussion

Hi there. My husband has been into BDSM since I have known him. We have a big night of it every Sunday without fail. It’s not really my thing but I have been more than happy to do this for him for about 15 years, he has a stressful job and I get that this is his release. We’ve recently moved to using a chastity device, I like the sound of having some benefit to me. It has improved my self worth - I like that he helps around the house with the kids etc. It could work quite well (even if it isn’t ‘my thing’) the trouble is he wants to “pleasure me” all the time and I’m just not into it. I’ll happily do all the other things that come with it, I feel like I have done A LOT for him. I just wish he could accept it is not for me. I still get pleasure from him, he just has this fantasy of my demanding him to go down on me every night and it’s just not something I’m into at all. I guess I’m finding it hard to put up with. He is obsessed with sex (quite possible an addict) and I find it hard to put up with the leering, whining, constant innuendos etc. I made a new set of rules that requires him to stop with all that but it hasn’t really worked well. If i mention he has broken rules and will be punished he accepts it, but will be in a bad/sad mood that really affects me. How should I deal with this? I find it really hard because he’s putting me off the whole thing. Any advice anyone could give would be really appreciated. Thanks in advance
