So my SO now when he gets hard it's never wet always dry but my previous it was always wet right before we were about to do anything. I know every guy is different but what can be the causes I mean of previous always being wet I'm guessing it was precum, and he didn't have any STDs or anything.

And yes I ment precum I know they don't get wet lol I was just wondering why some have precum before doing anything and others don't.
