I barely ever make any noises when i have sex or cum. I dunno, it does not cum (pun intended) naturally to me. I never understood this need to scream or whatever. Like Pierre Woodman, i like his stuff mostly but when he cum he yell so loud i litteraly have to mute the scene cause it annoys me and i fear the neighbors could hear.
In my case the most i will do is breathe a bit heavy especially if in missionary and my head is close to her, thats likely the only song she may hear. I think sometimes some girls may think im not enjoying myself cause im not vocal, but my satisfaction comes in face, if i smile and look happy/starre at you, its that im having a good time. But im too shy to pull out stuff like "oh yeah baby" or whatever.
I always wanted to say "dropppppping loads" as im about to do a facial like that dude in porn, but im too shy lol, could never do it.
