What Was Your First Time Masturbating Or Climaxing

I'm really curious about people's first time realising they could masturbate and their first time cumming both men and women.

My first time was at my aunts house me and my cousin cassie had been out with her to the big fair, cassie was 3 years older and we waited for her mum to fall asleep so we could play games. She put her tv on and muted it so we had some light and said to find the cartoon channel but I ended up on the sex channel. I knew what it was but had never seen it and quickly got hard. We watched it for a little and I noticed her hand was in her shorts so I copied. We ended up with our shorts off so we could see how guys and girls did it her pussy got really wet and sticky and I said it felt like I need to wee and started to shoot cum. It got on her thighs and the woman on tv made it look really tasty so cassie tried it and pulled a funny face. We cleaned up and decided to go to sleep. Auntie never found out and cassie never told. we still joke about it to this day
