I tried the Lex primal scream when I came with my gal and she didn't enjoy it. She said it hurt her ears and not to do it again. I do make the caveman grunts leading up to my cumshot and she doesn't seem to mind. Oh well, I tried.
My Filipina ex-wife was a BBC lover and even let her black BF knock her up so she wouldn't lose him! Joke was on her because he dumped her and said it wasn't his!
