Not working for me

Hi, I am new to using my MGX. I have tried it three times now. I use plenty of good lube and I use a enema before hand. I do not have trouble with insertion. I do not have any pain or discomfort while it is in. I have read everything in the FAQ's and a lot of posts on the forum. My problem is that it doesn't do anything for me. I relax, do the breathing and and contractions. I do not get hard unless I do it myself. I get no pleasure out of it. It just gets so boring. Last night after over a hour of relaxing and working it, I fell asleep. I woke of five hours later with it still in me, and nothing, no pain no discomfort & no pleasure. I feel that I got ripped off for $100.00 for the toy and lube. Any suggestions?
