Masterbating for my husband

I've been with my husband for 23 years I'm only 39 he is 43 I'm starting to feel like we r in a rut like he doesn't want to have sex with me at all. I wanna try something different and one thing is letting him catch me masterbating does anyone have any ideas on how I should go about that???🤨🤔🙄😏 Lol
