Actually a penis repeatedly bumping into a cevix can be as irritating as any toy. Or even lubes containing nononoxyl-9, which was so widely cheered about in the 90's has been found that this detergent based product can cause enough irritation to make micro tears in the vaginal mucosa making it easier to get an infection.
I haven't seen any studies on Cyberskin masturbation sleeves, pumps, or artificial pussies. I would invest in silicone if I were purchassing, or cover my cock with a condom (lubed inside and out for better sensation).
Talc may be linked to cancer, but pure cornstarch is great food for bacteria. (hey, I have sprinkled some on agar on top of some of my cultures for my own experimental pleasure and everything grew out faster on my cornstartch fed group. )Toy cleaner, wrap in really good paper towels like Bounty, was in toy cleaner or antibac soap again before using, and always inspect your toy for flaws. Men get skin infections too. Don't share porous toys. One person's normal skin flora might be your ticket to getting MERSA (methacillin resistant staph aureus)MRSA initially presents like a small boil or spider bite and goes into an ugly, fullminating cellulitis as it progresses. Some people are colonized with it out there in the population and are asymptomatic. Gyms are also a good place to get MRSA and other infections if benches and equipment are teaming with it and you have moist, open skin somewhere.
Lastly, I tell my patients who no longer have a cervix, that they will no longer have cervical mucus, and they also do not create enough vaginal secretions for comfortable intimate relations. (Their vaginal canals are now dead end cul de sacs, per se) I recommend lots of water based lubricants without glycerin,and moisture suppositories as well as lubes and I recommend dating the bottle or tube upon opening it. Cancer should not end intamacy, everyone needs it. )
Toys with phthalates can release toxins that also have to be processed by the liver and the kidneys, so their effects aren't just localized to the genitals. And generally they have degraded significantly within a half a year, so why take the chance on degrading and releasing toxins or harboring infection. They might be fun for a few uses and then toss. Up grade to better materials.
