Women don't like the fact that men and women are different

So I was having a conversation with my girlfriend about the fact that I have to use a different toilet brush than she does because she is so gross. I have no problem with her using the regular toilet brush in the morning when she does her hygiene, but I can't use that brush at night after I use the bathroom because it has her snot and blood and other stuff in it from her being so gross. <br><br>So she gets pissed at me for saying she is gross and she says that I am sexist for not wanting to use the same toilet brush as her. She says that women and men are basically the same and there is no reason why I should have a problem with using the same toilet brush as her. She even goes as far as to say that I shouldn't have a problem with intimacy with her because she is just as clean as I am. <br><br>I told her that she is not as clean as I am and that I can smell the difference between her and other women. I don't know how to tell her that she is gross because I don't want to hurt her feelings, but I don't want to be with someone that I think is gross.
