I had used this years ago with an ex who purchased it. This was the first guy I did anal with, and we tried this lube and one other kind. We had gotten the unflavored as I was new to all of this; I thought flavored would be weird! I really felt like this lube had eased me up to try anal, and I ended up loving it! You can also use this lube on toys too. He always got the lube out of the bottle and seemed to struggle to get it out at times. This was a thick lube, which I felt like lasted a good time too. This is a water-based lube and contains Deionized water, Vegetable Glycerin, Propylene Glycol, Polysorbate-20, Carbomer, Triethanolamine, Flavor, DMDM Hydantoin, Mathyparaben. It is also free of L-Arginine. This bottle also very clear of what it is as anal lube is written big on it. It is a 6 fl oz bottle and seemed to last a very long time! I also suggest if you try anal, it is best to still wear a condom during!
