i dunno man, i've had girls bite my ear before, i don't think it's messed up. as long as they aren't literally trying to eat my ear it's all good. i think a lot of girls do that.
It seems like every girl likes to bite, but occasionally you come across one that is just biting way too fucking hard to the point where its just painful and distracting. I had this one bitch bite my chin once too which was incredibly uncomfortable. Also some girls want to stick their tounge in your mouth too deep/for too long at a time.
it really is not that bad, but still, hooked up with this girl after she had smoked a cigarette like a few minutes before, worst taste ever, moral of the story, dont smoke cigarettes, they make you taste like asshole.
word, that's how i made my best friend quit smoking (when her and i were dating). i just told her i didn't want to be around her if she was smoking, because to me it was like watching her kill herself. she smelled bad, tasted bad, generally just really gross to be around when she had been smoking. after about a week she just quit. she had only been smoking for about a month so i guess it was a lot easier for her than it would be for people who had been smoking for longer.
