In the story "The Leading Man" we have a lot of sexual adventures for our key handed friend. It seem as though to become so-called normal or have something to connect with everyone else there a need to have sex. It seems that way for this character that is separated from society as different by virtue of his hands. I think the author did this to give him a more normal or regular person feel.
The romance first starts with a girlfriend, then some french fling, then finally his true love. This is similar to the blue eye beauty in "Girl who fell from the Sky". Sex was a way to cope with being different and for a night or a few seconds feel excepted. The blue eye beauty was used just like the leading man, in that there early sexual relationship seem to be for there partner a great idea to try something with a person who is deemed different or a freak. Both character were used for both sexual desires of another and to explode there freakish natural to them.
