Why bother avoiding him? Just because he happens to shove a dildo up his ass, it doesn't change who he is. So what if he likes doing that, to me thats not wierd at all, fuck it, whatever floats your bloat.

Your just going to have to accept that that is how he is. He's still the same person, your just going to have to accept that fact that he enjoys having a dildo up his ass.

You'll get over it, and you will feel normal around him again if you can just accept it.
