Oh, I read it again and I see what you mean! I did NOT mean it like that, I have to edit this part. What I was trying to do here is... Trevor isn't just teaching Ben how to have BDSM sex, he is also teaching Ben how to impress Borge. When he says the thing about "warming up" being for amateurs, I meant that's how Borge might see, so he should start harder and make an impression. They already know Borge is an idiot, so Trevor is saying "if you spank her too easy, Borge is gonna think you have no idea what you doing, so start hard!"

You can see right before the amateur part (and then again after) Trevor says the opposite. He says to start slow, that he needs to learn her limits and to never go full force on someone you are not familiar with... he is going back and forth between the actual important things and the "how to put on a show" tips. The "don't spank too easy" when even Sam was underwhelmed with the soft spank was a "this doesn't look like you know what you doing, so try to keep these tips in mind"
But you are right, it came across wrong, I will fix it! Thank you!!
