Super Slik Lube from SexToysUK when I got my first bigger-than-a-ladyfinger vibe, which is going back a good few years now!
Super Slik is a water based lube which comes in 100ml tubes and is produced by a company named Herrco in the UK. It's labelled as a non staining lubricant, which from my experience with the product I can vouch for, in that while I don't recall having explicitly spilled any, I've also never found any stains or marks from it either. So a definite thumbs up from that point of view!
I've found that a small amount goes a long way in use and the real value of this lube for me comes in that it feels so completely like my natural juices it's unreal. The consistency and general 'feel' of it is extremely close to my own lubrication, making it my number one lube for vaginal play.
It does work for anal play, and does the job well, but I do favour something a little thicker personally. It does have a slight aroma, but nothing unpleasant or overpowering, it's a pretty neutral scent (and just now, upon sniffing it, I've realised I actually find it very comforting! It must be a familliarity thing I guess!)
And, all in the name of science... or something... I have even tasted it! For you! Appreciate my dedication, people! ;) Anyway, having tasted it, I can confirm that it has a slight sweetness to it, but is otherwise fairly flavourless. I don't think you'd notice much difference going down on a girl who'd used some of this, put it that way.
All in all, a glowing endorsement for this one. It's my go-to-lube, and one I don't see myself without!
