To stay limp

2 days ago I had my sissy session right after intense sauna. I made comfort pose on bed and shibby audio hypnos ready. It lasted almost 2 hours and no contact with my girlcock was made. Mostly nipple play & inner tights massage with some gentle perenium touch. I ussualy eat precum or use it as lube, but this time i just left it to drip down in a stream toward my boypussy. I was able to ride waves after an hour eaven if I was rock hard the entire time. However I was not shakeing from pleasure when I erupted. Ussualy wearing panties helps a little to be at least Partly limp, cuz i have bed experience with chastity cages. Do you have any other practices?
