Masturbating As Long As I Can Remember

I am a 25 year old female and I have been masturbating as long as I can remember. I also am attracted to women and identify as a lesbian. As the title of my confession says, I have been masturbating as long as I can remember. Ever since I was about 5 or 6 I have found great pleasure in rubbing and grinding my pussy on or against anything that I can. When a little girl, I would spend a big part of the day laying on my stomach humping my teddy bear, the pillow, my fingers, or anything that I could find that would feel good on my little clit.
At about 10, my Mom and I went on a vacation for two weeks and we were stagnating at a hotel. All of my life it has always been just my mom and me. I never knew my father. There was only one bed in the room so Mom and I slept in the same bed together. After a couple of nights there, I woke up to my mom laying on her tummy with her hands under her and between her legs bumping her puss y against her fingers, just like I like to do. I knew what she was doing and understood what masturbation was after she was me humping my fingers on the living room floor watching tv. I was about 7 then. She didn't stop me but after I was done she had the talk with me explaining about what I was doing and that all girls and women do it. She told me that it was ok to do it around her,but if people were there, to do it in my room with the door closed. I asked her if she did it to and she said yes and that it feels good to her too and she usually does it at night in bed.
I found that there in the hotel bed watching my mom masturbating herself realized me excited and my pussy wanting to be touched also, so I rolled onto my stomach with my fingers between my legs as well and started masturbating watching my mom. My mom soon realized what I was doing and started watching me also. Mom started telling me that she liked seeing me do it as well. Before to long my mom and I were both getting ourselves off cumming together. That was the beginning for me of my desire for women. After that, mom and I would masturbate together several times a week. When I was around 12, I asked my mom if I could do it to her and she said yes, as long as she could do me. I also agreed and that was the beginning of my mother and I having lesbian sex together and we still do. I no longer live at home, but mom and I still have sex together whenever we are alone together.
I am curious how old other girls and women were when they started masturbating, and what was their preferred method? Have any of you ever had sex with your mother of other female family member, and what your sexual preference is? That is my confession, I would love to read yours.
