Oral Sex in Relationships

The act of sex helps cement a relationship and create an intimacy. But there is a real difference between playing tennis with some one and having oral sex with someone. And i think that there are relationships which force you to be fully acquainted with the most damaged and difficult sides of another person. You can't edit yourself in front of another person, the constraints of it. Your sharing the bathroom, your sharing the bedroom. There is nowhere to go. That was me at 22. Where do we go from there?
