orgasm when rubbing clit

so when I masturbate I usually just rip my clit A LOT and watch some porn. it takes me from 3 - 20 min to come to a feeling where my whole body is just shaking and pulsed w good feels :) . is this an orgasm? only problem is I usually can’t continue to run my clit after as it becomes to sensitive and I get scared. no cum really comes out it mostly just gets wet. should I continue? tips?
