I am also among those who finds it difficult to openly discuss sex among others.
This is different - the anal experimentation thread.
I think it is way too bad that anyone feels embarrassed or hesitant to say what's on their mind.
I wish I could go around and if someone asked "how's it going" I could say something like, "oh going just fine, read a good book last week, ordered a butt plug, jerked off last night, shot up to my neck, you know, the usual. And how's your day?"
Alas, I have not reached that place.
Someday.
