My mom allways catches me analy masterbating im a 17 yo boy.

Im 17 & bi. Im so used to getting caught doing gay things by my mom It dosent even bother me aneymore if she acidentilly walks in on me. Sometimes I dont even stop while having orgasims and all. I guess she gets the picture and leaves when she realizes that im not done yet. she doesent really seem to care either aneymore. I guess cuz she has walked in on me doing so many different gay things so many times. I like to use a large shampoo bottel with lotion as a dildo. She has caught me using that so many times now that even if im naked on my knees with it in my butthole I dont even have to try to cover myself up. Usually she will just leave and shut the door after she sees what im doing. we are both so used to it ,and comfortable with me being naked sometimes If she needs to ask me something real quick she can come in and ask me whztever and walk back out like its no big deal. Even though im butt naked with a shampoo bottel in my butt. i know this isnt completley normal but what do yall think about this? I dont really see the big deal if we are both not embarassed and both dont care.
