I've noticed this tendency in myself to really want to show affection in a way that puts a lot of people off - like, being hyper-aware of my need to hug someone, or put my arm around them, or possibly even lend them a kiss. I'm not as good with sharing warm feelings by talking - it's never enough to say "I love you." You have to say "I love you" a hundred times, while wrapping yourself around the person you love, in between an endless succession of kissing and petting and laughing and laying my head down on them. Trouble is, to most people, this is pure mush. With the less explicit shows of affection (arm around shoulder, etc.) it's at least an invasion of personal space, and/or just plain innapropriate and "weird."
This gets awkward when with someone in another Quadra. They're not as touchy-feely, and so I either have to tone it way down, or else make them feel dirty. Very dirty. (Teehee! )
