Ways to spice up our sex life?

Now don’t get me wrong I love having sex with my boyfriend just as it is, but I’ve been wanting to try new things. For the most part nothing is off limits, except adding more people (unless Harry styles volunteered 😌), so any suggestions are appreciated. We’ve tried toys, butt stuff (both ways👀), sexy names, handcuffs, blindfolds, sexy fits, and doing it in different places. I just wanna try something to spice things up since we’ve been kinda getting into a routine.
