This isn't meant to be a complaint, because I love my two Vixskin dildos, but I noticed something odd today. My chocolate Maverick is significantly tackier feeling on the surface than my caramel Johnny. Has anyone else noticed this sort of thing? I'm not sure if the different color has anything to do with it, or maybe it's a function of age? The Maverick is newer then the Johnny, but I don't remember the Johnny ever feeling this sticky. Just curious what would have caused this.
