Howdy deldoy, I'm not sure if there is a right or wrong answer to this question but I'm sure you will get lots off different opinions. Most of the time I jelq before I go into the Bathmate but then I jelq straight after as part of my routine and I repete this 3 or 4 times in a session, of course after 5 or 6 minutes in the Bathmate your junk will be massively engorged and look very impressive and the feeling will be amplified . I do tend to mix it up every other week using the Bathmate first then jelq, do both bud 👍
