I tried using KY in the past, but it work out well for me. I was introduced to this stuff at a local novelty shop a few years ago. Never had a problem since. I use it with condoms and all my toys, whether they\'re silicone-based or not. It is true that, if you\'re not actively using it once pumped out, it will get sticky after a couple minutes; I just pump out a small bit to help refresh it.
Tactical Tip: Don\'t squeeze the bottle to get the lube out! I actually cracked the bottle\'s seams one time. Luckily, I did the following 5 steps before the bottle started leaking: (1) Get your hands on an empty squirt bottle, especially one where the pump-cap portion\'s the same size as this bottle\'s threads. (2) Also ensure the pump is a lockable pump, like the ones on lotion bottles, so it doesn\'t squirt unnecessarily. (3) Rinse both the attached straw and pump carefully and let air dry thoroughly. (4) Trim the straw (still attached) at a steep angle, no more than 30 degrees. The trimmed edge should touch the bottom for max usage. (5) Screw it on and use. This should help you use every drop before you need to buy more. Plus, because you\'re using a lockable pump, you don\'t have to worry about spilling when either storing it for travel or in a cabinet.
