In this post, I aim to say a few words about why I chose the titles I did.
BestFriend -- This one needs no explanation, she is simply my Best Friend, and has been since we were eight. There are other people who may be closer to me or know more about my current life, but they do not qualify in any way as a best friend.
BelovedBoy -- As a somewhat aware non-heterosexual, I've spent much time looking for a good way to refer to my boy/girl/mtf/ftm/boi/grrl/whatever friends. Significant Other just sounds so clinical to me (despite xkcd's wonderful bastardization of the term), partner implies an eternity I'm not sure I'm emotionally ready to face, lover implies sexual intimacy, etc. I finally hit upon Beloved as getting the point across, and being entirely genderneutral.
BelovedDude -- See above. She would be BelovedGirl if she hadn't specifically mentioned that she doesn't feel the word girl fits.
ComplicatedBoy -- As per xkcd, I formally asked him to be my complication on Facebook. He is the mentally youngest of my current partners, I believe, which adds several layers of complication.
ComplicatedGirl -- She is not actually very complicated at all, beyond claiming to be heterosexual and having quite an interest in girls. The name serves primarily to tie her with ComplicatedBoy, as they have a very close relationship.
CrazyEx -- He is my ex. He is crazy. He fucked me up quite a bit, and I am bitter. He may very well do non-crazy things, but that doesn't stop that he tainted almost three years of my life by being a part of them.
DragonTech -- He is a professional theatre tech, trying not to starve. Through extended chatting online, I've learned that he tends to be draconic with his actions and avatar.
ExEx -- She is my ex-girlfriend. Who, during the summer of 2008, I began dating again. Ex-exgirlfriend. Ex-ex.
FatherMaster -- We are merely sexually involved, and theoretically not even that, He quite likes being in command of a squirmy little nineteen year old, giving him the master title. He is also the first person to ever be in a situation where they could bone fide hold me as I cry, and has spent much energy worrying about me and supporting me, giving him the title of Father. (My daddy issues will be a separate post)
Gentleman -- He really truly is. He is such a Nice Boy it almost hurts to think about. I'm still waiting for him to be revealed to have the head of his ex girlfriend in his closet, or something, he is that sweet and pure and good. (Pure is slightly of a misnomer -He's heard of Good Vibes, among other things.)
GirlfriendInLaw -- This is a technically inaccurate title, in that there is no marriage to cement the in-law title. She is the other girlfriend of my BelovedBoy.
Heartbreaker -- He was a high school romantic fling who dumped me, went out with this crazy bitch "friend" of mine for two years, and took something like a year and a half for me to actually get over. We are now quite close friends, but he remains the sharpest pain in my heart.
Kitty! -- The first time I ever met him, he spent the length of time acting more than a little cat-like. Old nicknames die hard.
OneNightGirl -- A girl I had a one night threesome with.
OneNightBoy -- A boy I had a one night threesome with.
Redhead -- And absolutely *gorgeously* so.
Regret -- There was a point in my life where I had to decide between continuing to date CrazyEx, who was local, or Regret who was quite not. I chose the former. I believe that my experiences have all stacked upon each other to bring me to the quiet perfection that is my current relationships, but given the ability to choose the other way at that point, I would have been hard pressed not to change my mind and save myself some pain.
ShibariBoy -- I picked him up this summer, and for a while we just talked shop, before realizing that the sextalk was getting more intense, and oh yes, naughty things wanted to be done between the two of us. We've still gotten little chance, but he is absolutely wonderful to distract my thoughts with.
