I'm aware that over time it will degrade latex so clean my toys carefully. Regarding it's use as lubricant of preference for anal sex, I am reminded. I hope you practice safe sex. If you do, please do not use Vaseline. That shit eats right through latex like acid in no time flat. DO NOT use. Vaseline is oil-based, and as such it can weaken latex. Also, you should use water-based lube with any silicone sex toy (like a butt plug), not.
