Well, in my case, I don't use that much lube, tbh.
I am circumcised, but they left enough skin left for me to be able to stroke it up and down without any need for lube.
Sometimes I use a cockring I have, to last longer and feel that orgasm denial. When I do so, the ring does hold my skin back and I do need to use lube. I only have water based lube, so that I can use it with toys or condoms without any risk. since I don't really use it that much for masturbating and it's more for butt stuff with my girlfriend or toys and such.
I find that when the lube dries out, it's easy to just spit on it a bit and it regains fluidity.
I also like to fap to the verge of cumming and stop it at the right moment so a bit of precum flows without me being done, and I use that plus spit to lube myself up.
With my girlfriend, we don't really use lube for vaginal sex, she has a lot of natural flow and always gets super wet. Also, when she sucks my dick, she gets it very wet. So those natural lubricants are what we use most of the time.
