Hello, When my anus is inserted, I get so vocal. I can honestly say that it just comes out. It is odd because I was not nearly as vocal as a heterosexual male even though I enjoyed it. Also, I have moments, because of the pleasure I assume, where I get an over whelming urge to rapidly buck my hips. Yes, I plan hip movement too, but I enter short periods when I just rapidly buck my hips. Usually, a short period afterwords, my inner thighs, thighs, hips, and butt muscles just start an erratic shake. Not a bucking, but like a convulsive shake that is completely uncontrollable. It is when I am really enjoying the anal insertion! Anyone else have this experience?
