Major breakthrough today

Hello, A little bit of background first. I have had a MXG for several years and have rarely used it until recently. The whole "stay at home" thing made me get back in the swing of things in the last couple of weeks. My first experience with it years ago was positive and within the first couple of tries I had an incredibly intense sensation with a racing heartbeat. I had been chasing that sensation off and on over the years but never really got back there and then got sort of discouraged, until today! The session today started with heating up the MXG with some hot water like I like to do to decrease the shock of a cold device. I then use the condom method with an addition of a couple of milliliters of lube in the rectum. I lay on my back with a memory foam pillow under the buttocks and a pillow on each side to comfortably support my legs in a spread open position. Today started as most sessions do with medium and hard contractions and then some relaxation. Nothing spectacular at first but then I decided to lay my legs down along the pillows and start a hard contraction. My left butt cheek started to spasm and then that rapidly progressed into a whole body writhing! I got an erection which rarely happens with Aneros sessions. Rapid sensual breathing and bucking of hips commenced. Very pleasurable! I let that ebb and then regained my breath and decided to leave it be for the day. Had some nice butt buzz for about an hour after the session. Looking forward to the next session!
