Looking for direction

Hi, I have had several sessions with pleasurable results, but I still have a long way to go.
In a couple of sessions whilst on my back knees belt feet on the bed, I had my legs muscles spasm, then my knees started to come together and fly apart, then I started getting pelvic spasms. Strangely I did not feel much anal contractions or PC contractions, at least not that I was aware of.
This led to a blissful feeling and I repeated it 5 times.
I am I being distracted with these muscle spasms, should I be concentrating on getting involuntary anal & PC spasms?
