Need to spice up my sex life

So my boyfriend and I have been together for almost 3 years now, we typically do the same positions when we have sex (missionary, I ride him, from the back) but I wanna change I.T up and do something sexy for him... any suggestions for new positions to try or some kinky things I could do to tease him and turn him on? I’m typically a more self conscious person but I’ve been more confident in my body and he has been patient with me so i wanna do something cute n kinky for him
