An estp here explained enjoying doing, performing during sex. That isn't aggression. That is action.
I know Ni types who enjoy utilizing motion in nonsexual and sexual situations. That doesn't mean they aren't moving, themselves, and that doesn't mean they seem nor feel inferior nor subjugated nor inactive. Surfing waves isn't inactive. Gulenko noted the value Ni types place on Se action. He mistakenly talked about one-sided respect and even superiority which can sway readers subconsciously. And the surfer's pattern seeking and insight and projection, utilization, adaptation inspires awe, too, not just the lake or ocean's motion and power, etc. Ni types get awed reactions from partners during sex, too.
Ne types I've known enjoy playfulness with a steady partner, ime. They are still adults, just innovative, whimsical ones.
Si types and I interact less, but I've heard them express what they like to experience, and no imbalance in maturity nor in age comes into it.
