A little frustrated... need help!

Hey guys, just a quick background: Im a 27 year old single straight male, I've had my MGX since last september, it kinda sucks because up until a month ago I was making some serious progress, prostate tingling pretty much all the time, there were some times where I even felt I was about to have an orgasm just by thinking about it.
So around a month and a half ago I had my first dry-o, it wasn't a SUPER O, but man it felt good, pretty much like a regular penis orgasm just more intense and focused in my whole perineum area, accompanied by some crazy body spasms.

But it pretty much went downhill after that. What I did notice is that If I start doing it everyday, the sessions start getting worse and worse and I get bored, I have to leave at least 3 days between sessions, anyone experience the same?

I guess what frustrates me the most is that the whole thing seems to be dependent on a extremely complex balance between being aroused, being relaxed, being well rested, being focused, keeping a fantasy in your head, not having distracting noises, not having distracting light sources, using the right amount of lubricant, etc etc it's soo damn hard... right now, regular masturbation has a much better pleasure/effort ratio for me.

I think having my first dry-o generated so much expectations in my mind, that it hindered my progress from there.

Im also worried that since my last (say) 10 sessions have sucked big time, Im afraid im unwiring somehow, I can barely remember what the p-waves feel like.

Sorry for bringing so much negativity into this board, i've been reading most of these threads for some time now and it seems like such a wonderful group of people, I guess it's more of a quick vent for me.

Also, at the end of dud sessions like these, I end up being extremely horny, but I have to resist the urge to jerk off since I feel somehow it could hinder my rewiring, im extremely ocd about it. I just can't understand how could it feel so good just a month back and right now it's pretty much nothing.

Any tips, words that could help? (Either way im NOT giving up!)

Thanks everybody!
