Which one to buy and getting rid of the pleasure (actually,the pain), tab

I think you need to explain what the plesure pain tab is.

Prostate pressure might be user-specific, not model specific.

@Charlie1 Each Aneros model is designed for different prostate sensations and you may need to try several before you find the one that suits you. The p-tabs are designed to provide a feedback loop from the prostate to the perineum and generally should remain. They should not be painful. You may want to explore the new "Trident" series of Aneros massagers which have redesigned tabs. I too prefer plastic. Good luck!

It feels like a dime digging into your taint, but guess what? The roughness goes away after only a few sessions. The p-tab is essential for the lever-fulcrum effect when contractions begin.
