Fudge it! Water pumping!

Ok I finally ordered a Bath Mate, after reading almost everything there is on the web about it. I know, I know I got brainwashed by good opinions that were probably hoaxed by people involved with the production and distrubution of BM.

So there is a big possibility that Ive just wasted money. Hell with it.

Ive have only one question if anyone could help out, is it ok to pump with an erect penis? I imagine it does get erect while in the process of pumping (never pumped before so I have no clue really), but is is alright to insert your unit into the tube while already erect?

I was wondering of doing some jelqs and then pumping, and after pumping rinsing with very cold water for a long time. Sounds good? (ok ok thats a second question! I know!)

May the force be with all water pumpers, Im going in!

Oh and Im going to take super potency pills after pumping to get even more blood into my unit. Any thoughts would be great.
