I was uncut until last year when I was circumcised for medical reasons. I, like you, saw masturbation lube threads and thought I would need to start using lube, but I didn't at all.
There's still a little movement on the skin on my shaft, which, having asked on here is the key, guys who have very tight skin with no movement on the shaft tend to need lube as it gets sore for them without.
As for the experience, I was definitely more sensitive before, so I felt more pleasure while masturbating. On the other hand, unexpectedly my orgasm is better now I'm cut. I get that same wave of pleasure centred on my balls I always had, but now, just after that peaks I get a smaller, 'bonus wave' more centred around the underside of the head of my cock that I never got before - it's very nice! So I'd say overall it evens out uncut vs cut, different but just as good.
Footnote: Sex is a little better cut, because, in addition to the above, my wife prefers it cut (slightly) and I get to feel more of her rather than my own foreskin as I fuck her, which is great.
