Okay, so I ordered this pump (the one in the link), and it seems really well-constructed (although that’s just based on my expectations, as this is my first such pump). I’ve used it a few times, following the suggestions of an experienced pumper. I’m a little bothered, because it seems like the skin at the base of my shaft is looser, and I turtle or at least turtle-neck more than I did before. Is this just a normal step toward eventual lengthening, or am I doing it wrong? I HATE the sensation of turtling and certainly don’t want that to be my only “gain.”
