I think about this all the time, what it would be like to switch bodies with your friend. To wake up and have to stay in their body, but both still have your own minds. I was having a conversation with my boyfriend about this, we both agreed that if we switch bodies we would have sex with each other, well yourself, but your mind in the other persons body. To see what it felt like fir the other person, some people might find that weird... Haha.
