I love watching girls on MFC but I rarely find ones who hold my attention. I'm pretty picky! Number one thing is the girl has to be INTERACTING with the room. It should have her full attention (unless she's replying to PMs, which I totally understand since I get bogged down with those too, since I usually have my topic set to 'Privates Welcome (PM first)').
I also want to see her FACE. At least the vast majority of the time. Maybe this is just because I'm a girl and girlparts aren't really a novelty to me. Even if she has a smokiiin bod and can move her hips like they're made of water (which does entrance me for a good minute or so, I admit), if I can't or barely get to see her face, then I'm outta there. I want to see real girls, not headless naked bodies.
They have to look like they're glad to be on cam! They don't have to have ear to ear smiles, but at least be a little perky! I haaate joining a room and seeing the girl sitting there with her face nearly pressed up against the monitor, looking glum or bored. And also POSTURE. Bad posture is one of my biggest turn-offs. Slumping is ick.
The more a girl moves around the more I want to stick around. I don't particularly care for dancing, but just moving around doing fun things, like dressing up or showing the room knicknacks or making their cat make funny dance moves. Even just bopping up and down a bunch does wonders for my attention span, haha.
Interesting outfits and making silly voices are also good ways to keep me around.
Now I want to get on cam and do all of the above.
