How should i approach this…

Gonna preface this by saying I’ve always had a pretty high libido (or at least higher than most of my SOs) and I’ve been with my gf for a few years now we live together now and everything. When it comes to sexually things, I’ve always wanted to try experimenting with different things like different positions, maybe get some toys involved, and she reciprocated that the few times we’ve talked about it in the past, sometimes we would share porn with each other. But shortly after we moved in together it feels like her adventurous side is nonexistent. We still have good sex but not as much as we used to. I feel like she’s content with the vanilla stuff we do and that’s about it. Not that I’m against vanilla stuff we have fun still, but we’re both in our 20’s and regardless of the things I’d like to try theres a lot that I would let her do to me that she’s expressed interest in, but it seems like she has no interest in exploring those things anymore and I fear that the sex is going to get stale or boring to me. Obviously it wouldn’t be the end of the world I have no problem masturbating but idk. Does anyone have any thoughts to offer?
