First time I ever saw naked woman

I was 9 years old when I saw my big sister and her boyfriend having sex in her room, both of them were completely naked. I was just checking on her but I got hit with the reality that a naked woman is a beautiful thing to look at. I was a little scared but mostly I felt a fear of missing out that made me anxious and jealous.<br><br>Idek why I posted this, maybe I just wanted to get this memory out of my head or maybe I want to see if anyone else has had the same experience. As a 4 year old my sister and I would get baths together to save water so I guess I was supposing a woman looked like a big girl down there but its not.
