Dull sex life.. help??

My s/o says our sex life is boring especially having our baby. and we do the same things every time. What else can I do to spice things up?? He’s a VERYYY kinky person (like bdsm) and I’m more vanilla 🙄 he wants anal and I try but we don’t do it often. Like once in a blue moon. I do try oral often but he says in general it’s become boring.. any suggestions???
