Newbie Helix Classic

Hey everyone. I just bought my first prostate massager and went with the Helix model. It looked like it was great for beginners so I decided to give it a try. I read all the stories of these amazing experiences. I didn't get anything really the first couple of times I used it. I think the first use I got some body twitching, but no tingles or things like that. I tried watching porn and got into a rhythm but not sensations past normal reactions to the porn. I tried different positions and nothing seemed to happen. I did all the exercises as well to the best that I could. I don't want to just buy another model to have the same results. Are there any suggestions to getting this experience started. Thanks guys.
