My Kirk and Spock do not have a sexual relationship with each other. My goal was to write a love story between them that did not involve sex and I feel like I pulled it off rather well, as do many followers of my stories. I had a blast writing them and I'm thinking about what I want to write next. My Spock and Uhura have sex in my story. :-)
cool then and I commend you for it. however I cant really say the same for most K/S fan fic writers who write K/S as lovers. some can get very catty about it and some write uhura as a hatful bitch who is in the way of kirk and spock becoming husbands.
however S/U fans can also be guilty of cattiness. they do at times write Nurse Chapel as also a hatful bitch who is in the way of S/U getting together.
this are one of the reasons why I don't get involved with ship wars.
