Actually, that doesn't always work. I'm almost always horny too, so I can kind of relate to her dilemma.
My suggestion, unless you are in a situation where you will be fine being horny all day or are able to be screwed mercilessly every few hours, I'd say avoid watching the porn for now. LOL.
I personally can't watch too much or I will have to sneak off to the bathroom several times a day....
Another thing would be to find a Master/Mistress. They could help you to get those urges under control. My Master is currently working on that with me. I've been without a Master so long and I didn't even realize how much I had let myself become uncontrolled.
