She don't like oral sex!!!

yes, others beat me too it. maybe she is embarrassed about you going there and she's worried you'll think its gross.

like others said she maybe embarrassed of some sort for you to go down there or it is less pleasureful. talk to your girlfriend and see what the problem is.

For some girls it does nothing. Ask her what about it she doesn't like because you may be able make her feel better and begin to enjoy cunnilingus.

I agree with what some of the ladies here have said about her perhaps feeling self conscious. Oral sex for a woman can make you feel very exposed and vulnerable. It may be the emotional side of things she is struggling with.

I know girls that don't like it. Some girls just don't like the feeling of it. Seems weird because most girls love it. But some really just don't think it feels good.

There is also the idea of maybe she is self conscious about it. Like it smells bad, tastes bad, etc, like the others mentioned already. Some girls are really scared of how they are down there and don't want the guy to be repulsed by it. And usually it's fine, but they are just scared of it.

she might think its unpleasant
not to be graphic but she could worry about her:
public hair, taste, smell, general appearance etc, even if its all fine

ALSO I sometimes get awkward because I can't kiss at the same time
so the guy is like REALLIY LOOKING at my reaction to what he's doing and I feel too exposed haha
dont know what to do with myself

hmmm
hope this helps =/

She might be very self conscious about the way she thinks it smells etc! Very common with girls and normally uncalled for. Try to get her to open up as to what her problem with it is!

Hey man talk to her. Ask her if she thinks it might be gross or something.

Im almost 100% sure that your girl is just nervous and thinks somethings is wrong with her.

Tell her there can't be anything wrong with it and what ever happens you'll stick with her.
