They are different, yes, like mentioned above. I, too, feel like a gushing/squirting O is more physically draining. Like I just don’t want to do anything afterwards except for eat and drink to replenish. However, I’ve had more of a full-body “tingle” (for lack of a better word) from non-squirting O’s and for a longer period of time. Like the endorphin high lasted for hours after and I definitely wanted to go again after a bit of rest (and snacks).
Every body is different. Every reaction will be different.
