My skin and mucous membranes are overly sensitive and I've found that all standard brands end up irritating in some form or another.
I've been using 99% Aloe Vera gel. Just the Aloe Vera gel with a smidge of preservatives (which are always needed, since otherwise the lube develops yeast and bacteria) with no perfumes or anything else added. To me it's the best of both worlds of water and silicone: it's slick and lasts longer like silicone, but washes off easily like water based.
I usually carry it in an unmarked bottle (I buy a big container and transfer it) and have had guys commenting on how they liked the lube and asked me where I got it, or if I made it myself.
I used to also make my own lube from golden flaxseed which is absolutely top tier, but a hassle to store and there is a bit of a (not unpleasant) smell.
