Previous Progasm use and Nipple orgasms from girlfriend

Hello there, this is going to be a loong post. Something very odd and wonderful happened to me recently.

I'm a bit of a lurker and don't post much atall (my last post was in 2011!) but I have been experimenting on and off for a while with the Progasm.

Since I have used it quite infrequently over the last couple of years, my progress has been rather spotty. Some sessions were extremely nice and ended in what I would describe as a Super-O, while others never really progressed past involuntary muscle spasms and the like. I think this matches what a lot of people experience as you REALLY need to be in the mood. Having a really good session involves a lot of planning and patience and I usually end up being impatient and just having a normal penile orgasm.

Now, I haven't used the Progasm in at least 3 months and my prostate had been pretty silent in that time, with none of the warmth or unusual feelings I was getting when I used it more actively.

I have recently started getting physically intimate with my girlfriend and I found out that she really likes having her nipples played with. Even though she is multi-orgasmic, she never had a nipple orgasm before but after hours of fooling around I started stroking them slowly and she started having loads of small orgasms. She must have had about 10 or 15 by the time she asked me to stop.

Afterwards she tried to return the favour and stimulate my nipples - something I had never had a great deal of success with myself. I can sometimes get sort of nice sensations when I've tried it myself, but it never felt all that special. Well, when she started doing it (partly as a joke, I think) I wasn't really expecting anything but after about 10 seconds I felt that old familiar involuntary flutter in my pelvis and a growing warmth. I started to breathe a bit more heavily and my hips jerked once or twice. She was pretty surprised by this and kept going. The sensations and involuntary leg spasms kept getting stronger and stronger without any mental effort on my part. After about 2 minute of this I started to gasp and convulse as I felt this amazingly satisfying warm rush spread up through my pelvis and dissipate around my lower body - it was definitely an orgasm!

I was absolutely stunned. I had never managed to get non-ejaculatory orgasms this easily with my Aneros inserted, even when I was touching my nipples! I can only assume that the rewiring that had happened in my brain was still dormant there and her stimulation combined with my extremely aroused state sent me over the edge.

Since she didn't know about my previous Aneros use I didn't want to weird her by asking her to keep going (although she seems quite keen, to be honest), but it felt like I could have easily had more.

Needless to say, if she's up for it then I'm definitely going to ask her to try that again!

Has anyone else had such success when someone else was stimulating their nipples?
Even though I barely use the Aneros any more, could all that rewiring still be there?

Thanks.
