Why do women bite their lips?

[Anonymous]

Every time I give my girlfriend a passionate kiss, she bites her lip.

I'm not saying I don't like it, I just would like to know why.

When do you normally bite your lips? during sex?, foreplay?

thanks

well we do it because...we are so into the person and when making out if we get hot and really into it...it comes naturally ...some guys do it too

I always bite my lip when I'm horny or doing something sexual. I don't know why it just happens. One of my guy friends is always teasing me because they can tell what I am thinking about. They think its because I like things in my mouth (which I do but I won't admit it).

I do it because I enjoy kissing. When it's passionate kiss I bite to kinda I don't know keep that moment for a sec longer. But it also helps when trying to be sexy.

Some girls do it to exude more sexiness and get the guy more excited. Others may do it because they are really turned on by the guy.

When I do it, it's usually just like a reflex... My boyfriend told me he liked it, and I'm like, "What? When did I even do that?" I don't even notice myself doing it :P
