Thanks for the input guys!

to clear things up a bit my experience was not anywhere near being scary or disturbing enough for me to stop practicing. It was more of a "what the heck is going on" feeling then a frightening one

I just remembered some questions that I have

first off when doing genital stimulation it is going to to be done while breathing in and the keysound is done when exhaling on the same breath if I am correct. Now my question is what if it takes a longer period of time to complete the genital stimulation then it does to inhale? should I continue to stimulate while exhaling and wait for the next exhalation on the next breath to do the keysound?
