Is it the overtly sexual nature of this that you find shocking? And - intensely personal question incoming, feel free to not answer - has he ever shared this particular kink with you personally, and is it the kind of thing you'd be down with?
Not at all. I knew he loved giving oral sex and this has been a huge part of the relationship. We have talked alot about our preferences and have explored a lot together. We both have our Kink and our Kink seems to mesh quite nicely. Again --this is why it was so shocking to see his post. We talk about everything--except this.
