So yeah I bought the MGX a month ago, tried twice at first, felt kinda silly and never really felt anything so I stopped. Last night I busted it out again and actually got to the point where I can feel the feeling building up, and my heart started racing, but I got scared 'cause I have never had this feeling before, so I don't know what my body did but it subsided, and I can never get to that point again. I am going to try it again tonight. *Fingers crossed.*
Or maybe it is because I got the wrong model? Should have I gotten the Helix instead? I mean I am already having enough trouble inserting the MGX. Not like having difficulty but I can definitely feel it go in there, as I am not really an experienced anal player, this was actually my first anal play experience.
Definitely your feeling either silly or scared is getting in the way. It ain't going to do you any harm. On the contrary it will do you a world of good, and the very worst that can happen is that you'll have an orgasm and ejaculate too soon and it's all be over till next time. So don't worry, just relax and enjoy yourself.
You're definitely on the right track. I think what you had was a very normal reaction to a very new bodily phenomenon, so, as GrandTiger said, don't worry about it! You may not experience these feelings again in the next session, or even in your next few sessions, but regardless, now you're better equipped to cope with them whenever they may next begin to come to the surface.
Enjoy the ride, it's all bliss!
