Spicy new sex with your partner?? Help

Okay so me and my boyfriend like spicing things up in bed . But I’m kind of out of ideas and money for now .. this is all we did so far .. regular sex like missionary back shots , oral , side , shower sex , and idk but it turns me on when we have to be sneaky and quiet so we did it in the bathroom when there’s someone in the next room , we went to a hotel had sex there on the hotels balcony, I did like a hand stand he fucked me that way , we fore played I was dressed as a slutty maid and made him be my “slave” I wanna get a toy and have him use it on me .. so what are some things I can do new to switch it up ?
