I am not DLD, but ... Considering you got the Extreme
X40, with the hand ball pump, you don't need Wine-vac! The ball can get you to the same intensity. Good choice, happy pumping!
Just don't go too hard in the beginning. If you haven't pumped before and
X40 is your first venture; use the pressure you can get from the pump with just the pushing movement. Get used to that first and then start using the ball.
Hard to recommend a set time when to, but not knowing your history, I'd say just ease into pumping in 1-3 months. Sounds like a lot I guess; listen to your body. Big enlargement just doesn't happen overnight ...
