The aneros prostate massager is an amazing toy in my experince. Once it is inserted into the anus, it massages the rostate from internal anal muscles.

So there is no need to move the toy at all or do an internal prostate massage with your fingers.

Aneros Progasm Prostate Massager Tips

Make use you use lots of lubrication in the anus before insertion of the aneros. While butt plugs are great for their intense sensation of fullness, butt plugs can also be used to relax the muscles in the anus prior to deep anal penetration.

Think of it as an anal warm up.

Start of with a couple of fingers to get the muscles generally relaxed. Then insert the aneros into the anus. Leave the aneros in for 10 to 15 minutes. This will cause the muscles in the anus to relax and open further.
