Newbie here

I am trying to find something to maintain longer and harder erections. I plan to start jelqing more often and I want to try the Bathmate. My GF and I want to try the Clone a Willy kit but I have trouble keeping a solid erection and want to make sure it is a replica of me full mast. Any help here?

Jelqing helps with circulation,edgeing helped me get better boners also that's worth a try
