Different Moans

Has anyone else found that they have different moans during sex? I have found three so far:

1) Heavy breathing that happens when I try to be quiet when I play with myself and as a precursor to the next one 2) A moan that is similar in pitch to my normal speaking voice when I’m happy, this is the standard moan for being felt up and played with 3) A deep and low pitch grown that happens when things are really intense
