Felching heavy loads out of her ass wasn't what I imagined I'd be doing when I first met my wife. Here we are!! As I wrote in a previous post if I had one hole to clean it would always be her ass.
My wife feels similarly. She enjoys emptying mens' balls but she doesn't like the presumption that she will always do so. If the guys are nice to her she will; if they're assholes she's gone.
That happened so long ago I can't remember how I felt. It's happened many times since so I got used to it. I must admit it was inconvenient during the heavy c hild rearing days, but it passed when they entered puberty.
