All right, new and improved, it is! I’ll be adding to this often, simply so I can keep track. And if you’ve got anything to suggest, do it! I enjoy random fandoms, after all, and you might come up with something I’ve never thought of.
Note: I'm slow. I'll be on talking OoC'ly, but sometimes I just don't respond for a bit. Have patience with me?
Turn Ons:
Long Scarves and Black Gloves
Light Bondage/Power Play
Item Insertion
“Older” Characters (25-60)
Plot
Imagery. I don’t always manage to pull it off, but I love seeing it.
Unrequited Love
Cross Dressing (especially if the man in the dress and heels has a beard)
Double Penetration
Turn Offs
Under Age-rs. Sorry, just not my cuppa, and I never want to see Chris Hansen at my door
Particularly effeminate personalities. You can look like a girl, just as soon as you sit us
down to have a nice talk about our
feelings, I might gag.
Too Pretty Characters
Playing male/female pairs. Only happens once in a blue moon.
Anthropomorphic Characters. Again, not my cuppa in general.
