The title is self explanatory.
Good Regulation of Tongue to Lips.
I haven't kissed a lot of guys (max 10) but one thing that I love is when a guy has a handle on things and takes charge. The best kisser whom I've had the chance of locking lips with was incredibly skilled with his toungue. A lot of guys just shove it in your throat, but this guy was playful: he'd initiate a little wrestle with my toungue, and he was generally really adventurous around my mouth. That guy also had a lot of creativity - I would have been happy to make out with him for hours If you have a boring kisser as a partner, the fun really goes out of it.
Also, I think stubble is ridiculously sexy, but not when it's being rubbed against my face like sandpaper. Ouch.
