I probably shouldn't tell you this, but I jack off to the ongoing saga of my friends wife cheating on him.
Dude, that's too much information. You sound like you're hot for her.
Yes, the more of her the better.
I understand that we don't control who we're attracted to.  However, it's important not to act on these impulses or desire harmful things to happen to friends because of the fact that we're are attracted to their partner.  That could ruin your friendship!
No, after this conversation, these thoughts will never make it outside the gates of Fantasyland.
That's good to hear. I'm glad you appreciate the potential consequences of your behavior.
