This stuff is great, and that's surprising because I completely expected it to be creepy and gross. In all actuality, Bad Dragon's own product "Cum Lube" is pretty awesome stuff. The bottle describes it as "a white-tinted viscous lube, similar in appearance and handling to real cum, only much easier to obtain in quantity." And it is, really.
Cum Lube is a water based lube, so it's safe for use with silicone, which makes sense since Bad Dragon produces fantasy inspired silicone dildos. No funky smell or flavor that I could detect. The four ingredients are listed right on the bottle, but two of them are parabens (propylparaben, methylparaben) so if you are Paraben-sensitive that might be something to consider.
I did the classic dime sized amount, rubbed-between-fingers test, and it took a full minute before there was any drag between my fingers at all. In fact, my fingers were getting tired from sliding together so fast for so long. Of course, exposed to air, you're just not going to get as lasting an effect as internally where your own liquids and warmth will amplify the effects of lubricant, so a full minute was pretty impressive. The consistency is a little thin, and especially with body heat it gets a little runny, but it doesn't insta-absorb into the skin. As it does though, it doesn't leave a greasy or sticky film, and dries quite smooth. Nobody likes to feel like they need to book it to a shower after using a bit of lube.
Of Cum Lube's texture, I will say this, there can't possible be anything as stringy and stretchy as this on the market. I'll be including a video with this review to show you, but this stuff is seriously stringy. And the strings can get some serious length too. So a little goes a long way, Bad Dragon sent me an 8 fl oz bottle with my Xenogon, and while it has quickly become my go-to lube for the past month, I've barely made a dent in the bottle.
