The masturbator sleeve is made of silicone and has no temperature, but if you want your masturbation cup to be as warm as a vagina, then you can use the heating rod to preheat the sleeve. Some heating male masturbators with built-in heating or heated bases make this job easier. You just need to warm up the sleeve about 15 minutes early and you can enjoy a game of next-level comfort.https://www.xspacecup.com/
