I fucked sooooo many of my girlfriend's BF's too. ..I'm so naughty! ;-)
You're not naughty, it just sounds like you're a narcissist and enjoy hurting people. These people your hurting are not really your friends, because you have to be a friend to have a friend.
Your going to end up a lonely bitter person if you keep on this path.
Also, one day you may fall in love, and when you do this could happen to you. The Universe has a way of leveling the scoreboard and then some. Paybacks are a bitch.
don't listen to #2.. there is NOTHING wrong with being a whore. It's a good thing. I'd love to date you and share you with all my friends and even some strangers.
