Is it normal that i masturbate infront of my family?

I am a Mexican/American female,named Celia.Me being as attractive as i am,I like showing off my body.Its not Un likely that you would see me masturbating somewhere,leaned up against the hallway wall,the staircase,under the table during dinner,and even while helping my brother with his homework.Infact,im allways naked around my house!I started this when a was 13,One hot day,here in California.As the air conditioning turned off,So did my clothes.I got to the point when i was in a bra,and a thong that was pulled aside my clit.I was in the kitchen cooking with my mom,which made the heat in the kitchen next level.My mom was wearing a tight tshirt,until she said,"Wow,its really hot in here,isnt it?" I agreed that it was,and even made a joke by saying,"I think i may be over dressed for this weather!" My mom replied,"Is that why your panties are pulled aside your lady parts?" I got embarrassed,and when my mom saw this,she said,"Well look,if it makes your feel any better," Then my mom pulled her panties down,leaving her entire bare butt exposed,as her shirt was short.By mom being bottomless,i looked behind,and saw my brother in the living room,staring at moms butt! That was my Que to take off my thong and bra...The feeling was very refreshing and cooling.Ever since then,i decided to stay naked around the house.Soon after,i discovered the intense experiences of masturbating,and made no effort to hide this,or clean up any messes.My mom would often tell my brother to clean up those messes!
