Condom? (and a couple other questions)

Three quick questions for you experts about the Helix Syn Trident I just got today. It’s so nice and new…I hate the idea of having to stick it in my ass lmao! But having said that…..

1. Do you guys put a condom over it or not? I’m obviously going to clean it, but I’d like to keep it from smelling too much like ass….if you know what I mean.
2. Also, what do you use to clean yours? Soap and water, or stuff like rubbing alcohol and hydrogen peroxide?
3. Finally, what does everyone find is the best lube? Water-based commercial lube or stuff like coconut oil, etc? All I know is you’re not supposed to use silicone lube.

Any experienced users who are willing to guide me with some advice would be awesome. Thanks for helping!
