I've only ever used KY warming and something from Spencer's that I don't even remember the name of (I was 15 and dumb ). I had no trouble with the KY but the other one burned like hellfire and afterward when I looked at the ingredients I noticed it had menthol in it so I chalked it up to that. Menthol should be cooling, not warming! But as far as I know, some of the ingredients they use, like menthol, to create sensations can be extremely irritating. I don't bother with warming lube anymore.

I used a natural one once and it felt like i was on fire, so painful!!
