Intense twitching..looking for feedback

Hello all,

When I voluntarily contract my pc and anal mucles I often get intense twitching which feels good but often ends in frustration. I haven’t seen anyone talk about the twitching as much. I considered contractions as bigger and not as fast as the twitching. Is intense twitching a part of the journey?

From the feedback I have read I assume I just need to relax more and focus less on voluntary contractions. I also find it difficult to tell the difference between anal and pc contractions.

Any feedback appreciated.
