my Partner and i are monogamous and fluid bonded, we don't always boil or sterilize our toys more than washing with hot water and antibacterial toy cleaner, but Wwe still stick to silicone and glass. i'd gladly consider ceramic, steel or wood but Wwe just haven't gotten around to adding these to Oour collection. Plastic is also relatively safe, but i just don't like the way it feels.
Jelly, latex, pvc, vinyl, rubber, etc all tend to have a smell, may off-gas chemicals, cause allergic reactions, irritations, infections, etc. Plus, it's not fun to think about, but yeast infections and BV happen, even in clean, healthy, monogamous women. Toys we can clean and sterilize as necessary are safer because Wwe won't reinfect each other. As two female bodied people, another concern is introducing the vaginal flora from one of Uus to the other which can offset pH and +/- bacteria balances. Plus porous toys can harbor fluids and things that can turn to bacteria and can cause problems. Not worth the risk to Uus. Plus, you absolutely can't switch between using the same toy vaginally and anally unless it is sterilizeable.
It's not just about possible disease transmission. Silicone, glass, sealed wood, silicone, metal, and ceramic are just more hygienic and eliminate allergens and reactions, as well as simply not exposing your body to potentially harmful chemicals. It's just safer to stick with non-porous materials, even with a fluid bonded, monogamous partner.
