Lost my kink

I used to be really into the idea of trying out lots of different things sexually, but I just don't have any interest anymore. Before me and my partner became a couple we used to sext all the time and talk about the things we wanted to try, but our sex life hasn't really lived up to that. Occasionally he'll take charge in bed and we'll do some different stuff, but not like I used to want. For the past few months I've barely had any sex drive, so even giving/receiving oral makes me feel awkward. I haven't really spoken to him about it because I didn't really notice until recently, and I've had some other stuff going on so there hasn't been a good time to talk. I have loads of outfits and toys that I haven't even looked at in like a year, I go for weeks without masturbating when I used to do it pretty much daily. I just want to know if you guys have any advice on how to reintroduce this stuff into my relationship or if any of you have similar stories of this happening for you
