This is my favorite toy of all time the
Aneros Male G-Spot Stimulator.

Now, it doesn't work the same as a dildo. You put it in and it might not seem like much but you have to give it some time. You lay down, relax, and gently squeeze your butt cheeks together. Okay, I know it sounds weird, but trust me. You put on some soft music, watch a porn or let your fantasies run wild in your head, and keep squeezing on and off over the course of about half an hour to an hour. What happens is the Aneros gently massages your prostate, so it may feel okay at first, as time goes on it feels better and better and before you know it that sound of someone moaning out loud that you hear is you!
It's not a toy for someone who likes to get in, get off, and get out. You have to commit to it, do it right and give it the right amount of time. But if you do that, the rewards will be well worth it. :)
