Sleeping with yourself
From: Data Logan
I applaud T for being willing to admit that she would probably be willing to have sex with a past or future version of herself.
Remember that book-turned-movie "The Time Traveler's Wife"? The time traveler in that story--at least when he was a teenager in the novel--did give himself blow jobs. As he describes it, it's what you do hanging out in your room with yourself for long periods of time waiting to return to your own time. The father walker in on it, seeing his son getting a BJ from a guy, but not identifying the other kid as ALSO his son, and therefore not realizing the time travel aspect of the situation. So the father thinks his son is gay and not understanding he was just getting himself off. And the son lived with this because the truth--that he was a time traveler--was something he wanted his father to know even less than the fact that he was a little gay (for himself).
