Had a good session today where it felt very pleasant from the start and in about 20 minutes I was able to get full body chills and uncontrollable muscle spasms and body shaking, twice, lasting at least 20-30 seconds each. It felt so amazing but it was more the response to the pleasure building, I still wasn’t able to achieve a super O. Note- I have achieved a super O only 3 times in having my aneros helix for over a year.
