Pumping in the bath is awesome if you have the time. I never do though. I always pump in the shower. I fill the unit up with water, get a semi, insert, then sit down to do the pumping. It's better to sit imo because you can be more relaxed that way, which is key when first starting out.

I think the bathmate is one of the best things a guy can have to naturally enhance himself. Never have to worry about subpar erections again.

And yeah, using it when you know you're going to be having sex later on is the best as the pumped effect can last for half a day or so.
