The biggest issue with PVC toys is that they can never be properly sterilized. Because PVC is a porous material germs and bacteria can get deep inside of it where it’s impossible to clean.
A cheap condom would work great for keeping the toy clean, and if it breaks being quick to wash the toy with soap or a disinfectant toy cleaner should be enough to prevent any issues.
Enjoy your new toys!
I'll offer the counterpoint that most sex toys for personal use don't have to be sterile. Clean/disinfect with soap and water before and after use and you'll be fine as for disease vectors. (Consider mild soap if it's for inside use)
I would however suggest cleaning the toy even after use with condom, most condoms are covered in spermicidal lubricant you'll want not to get caked on your toy.
Thank you <3 With what the other kind peeps already told me I'll def be using a condom next time! I also already have some toy cleaner so I got that covered too :P
