I was told it was “for hygiene” but now I’m questioning what really happened

I’m in my twenties now, from India and recently I’ve been seeing people on Reddit sharing their childhood stories. It made me think about something that happened to me when I was a kid, which I’ve never really talked about before. I was in Class 3, between 7-8 years at the time. My grandfather used to do this about once a week, usually on a weekday when my mom would go out for some work. I would be at home with my grandfather. This went on for a few months, until my mom stopped going out on those weekdays. Before my bath, he would touch my private area and apply coconut oil there. He told me it was good for health and that the area should be kept clean to prevent infections. He specifically told me that the clitoris was a sensitive area and that applying coconut oil would keep it healthy. He would also tell me to spread my legs so the area would be clearly visible while applying oil.. I was just a kid, so I believed him. I didn't really understand what was appropriate or inappropriate. He was my grandfather, so I trusted him and didn't think much about it at the time. Now that I'm older, I sometimes think about it differently. Was there actually any legitimate reason for doing this? Is applying coconut oil to the clitoris really something that is medically recommended for keeping it healthy? And why would he need me to spread my legs so he could see the area? The fact that it happened repeatedly, usually when my mom wasn't home, is something that makes me question it now. I honestly don't know how to interpret this memory. I'm not trying to make a serious accusation based only on something that happened when I was a child, but looking back at it now, it definitely makes me uncomfortable. I’m sharing this because I saw other people talking about their childhood experiences and thought maybe I should finally share mine too. I'd genuinely like to hear what others think. Was there actually a health or hygiene reason for this, or does it sound like his intentions were inappropriate?
