Is exaggerating the same as faking it?

My SO likes to hear me moan and be kinda loud in bed. Which I don't mind at all and am naturally loud anyways but sometimes I've already finished like twice and I know I'm probably not going to finish again even tho it feels good so sometimes I'll exaggerate my noises, I don't lie and say I finished again but he finishes faster when he hears me... Is this faking it or lying? Am I the only one that does this?
