It's such an intense rush letting your instincts take over! You can just go full monkey brained and fulfill your sexual desires free from the front you put on every day. And it's amazing when someone enthusiastically submits to you and gets pleasure out of being roughed up a little bit with hair pulling and the like.

I'm not super sexually active but I do hope the girlfriends I've had sex with have enjoyed it! I would like to start having sex more casually though.
