a question

[airpud]

Guys, forgive me if this sounds like a dumb question.

Why would anybody do bi-directional now that we have air?

Isn't air more effective and less painful?

I balloon now and bi-directional is dangerous anyway, as well as painful. I know first hand. Never again.

There is one thing I would say. I know that feeling something down there, even if it's slightly painful, is somehow reassuring because sth is happening. But with my balloon it's not painful and I can do it all day.

Ballooning is the solution I have been dreaming about for two years and finally I use it!
