If by "go dry" you mean you don't use lube, that's acceptable. The concern -- as I'm also circumcised -- is that you don't use much pressure whilst masturbating as you're building up more of a thick skin on your penis. By that, I mean it will reduce sensitivity. If you use lube, this will reduce the abrasiveness against your penis skin.
I don't produce pre-*** ... or if I do it's very little ... and have learnt to use very little pressure with my hand unless I'm using lube. I suppose it's all personal preference though. Agree?
