Women sometimes have stains in their panties due to blood from their periods. It is hard to get out the stain if it sets, Even if you bleach them. However, every woman should know that you dont wear them when your man is around and can see them.
If they are skid marks, then....that is just not lady like and I am embarrassed FOR her. That is something that is tolerable when you are a kid, but not when you are an adult.
If it is white and chunky, she might have a yeast infection (in this case you guys should not even be fooling around with her in that condition)
But then again you cant expect to just go down on your girl after the whole day is over and she has'nt taken a shower yet. The pussy is constantly cleaning it's self out 24/7 and this produces "moisture" down there which, if you dont maintain it, then yes...it can get bad. Women just have a whole lot more going on in that area then men do, and it is alot more maintainence that's all.
Just tell her, in a mature way, then that way she is aware of this ok? I would be pretty fucking pissed off if I knew my boyfriend would come to a fitness board to discuss my "pussy mishaps" to people he does'nt know very well instead of telling me about it. Maybe she does'nt know that you feel this way.
This whole thread makes me embarrassed.
