bae. let's spice things up

Hey guys. I'm just get down to the nitty gritty. So I'm at home and me and my husband (3 yrs) watching Netflix and chilling. Then outta nowhere, he says "bae. Don't take this wrong way but I wanna spice things up in the bedroom. Things feel routined. Like I wanna try sum new. So I'm listening and I said "okay. I feel the same way too but didn't wanna hurt your feelings" and he was like "what?"  Then says "okay. I wanna try sum. Anything. A toy with you. Or anal. Anything." so that night, I attempted to try anal while we was having sex. But this is where it's suck. When he tried to entered. I literally felt like sum was tearing me into. He got like the tip in. (He had lube cuz I said let try anal that night and so we research and bought sum lube) And I back out and he got mad cuz he was totally into it and tryna be gentle. I told him I'm up for anything but that. But he was like "once it's in, itll be okay and I wanna try sum new or let me sum with you cuz I'm tired of the routine sex." So y'all. Please don't be be too harsh but what can we do? I just wanna go home when get off tonight and do sum new to him. Should I buy a toy? What can I suppose my husband with? If anal, tips please for the leash painful because he is very well endowed. Huge tip
