Best lube?

Hey everyone! So my boyfriend's lube (KY) started to make me burn a little bit. is this normal? is this trying to give me some sensations.? We also are a little bit kinky and we like to try new things. We saw some of that IcyHot lubrication and condoms but our kind of hesitant to try it. Does anyone have any experience with that? Also what is the best lubrication I can use.
