I think that what you feel emotionally from a movie, show, porn etc may excite you yes, but actually doing it, irl, can be extremely different.
Now some will say it's even better irl! But you just don't know that yet. And there's certainly no rush to find out.
But it's very smart of you to be aware of this part that you have. Maybe get to know it & handle it.
I hope the T helps.
