The P-Plug is appropriately names, because it's positively perfect for pleasing the prostate.
I can't promise the P-Plug will work for everyone like it has for me but, it's been a few hours since I used the P-Plug and my PC muscle is still flexing and sending little orgasmic tremors through my whole body. The P-Plug may be a bit large for beginners but, I highly recommend working your way up to it so you too can enjoy it's many pleasures.
The most helpful critical review
In motion, I really enjoyed the P-plug. It made a nice little targeted dildo aiming right for my P-spot and felt great going in and out. As much as I liked using the P-plug as a prostate wand, I have to deduct major stars of the lack of quality control, poor manufacture (seriously, unmolding damage?), and the fact that the base is so badly designed that I got injured.
Ignore the name: use the p-plug as a prostate wand instead.
