Bi boyfriend

Hi everyone! I've been with my boyfriend for over two years and recently (past 6 months) found out he's bi. I don't have an issue with this but I'm struggling to come up with ideas to spice it up in the bedroom. We've got beads, dildos etc but he's always wanting me suggest things. We're alone tonight as I've bought some new sexy underwear. No shops open now but does anyone have any suggestions Things I can do to him?? Xx
