I am using a medicament internally (vaginally) that contains mineral oil. I know I shouldn't be using latex and rubber, also I have found the following information:
Mineral oil may cause damage to sex toys and other items. Generally, items made of glass or hard plastic are safe to use with oil, but rubber, latex and soft plastic will break down with exposure to the lubricant.
So I suppose silicone toys would be off the question, too? And basically anything? I was hoping to be able to use some of my kegel balls, but I guess that's not going to happen.
P.S. I should have probably put the topic in the Sex toys question, but can't move it now.
