I turned my mom into a pervert, please help!?

rst of all this is NOT a troll question. i am 100% serious and need help. i was talking to my mom about how its possible to think cartoon characters are hot, and i mentioned furries (google them, they are like people, but with animal features) nd i showed her a picture online of one. a few days later i opened up her laptop to use it nd her wallpaper was two lesbian furry dogs "doing the do" nd i brought it to her attention, nd instead of being embarassed or anything logical, she tells me after we talked she looked up furries and "found a few she liked" nd then showed me some of them. they were really obscene, so i just left, but now she is very open about it and i can hear her masturbation toys thru the wall and she does it about 10 times a day. she was never like this before. what worries me even more is she seems to be into more hermaphrodite/lesbian pictures and videos rather than straight ones, which leads me to believe shes bisexual now. and she told me that its ok if i want to watch porn, as long as its not real people, because "thats repulsive and degrading"!!! i cant stand listening to her and sometimes she even plugs her laptop into the tv in the livingroom nd looks at it( doesnt masturbate to it, just watches it, and i walk out nd see it then turn around nd awlk back in my room, only me nd her live in the house) she thinks its ok to talk about certain ones she likes and stuff like its a casual thing. just a few days ago she showed me one and said "this one is my favorite, it really turns me on!" i actually left the house for a couple days because its so disturbing to me. please help! im soo... confused right now. i really need help, what should i do?!?! why is she like this now?? what can i do to stop this. im afraid shes gunna mention it to someone outside the family which would be TOO embarrassing.
