Did I abuse my cousin?

English is not my native language, so excuse my mistakes.
I've had this guilt deep inside me for a long time and I've never shared this with anyone, I had second thoughts about posting here but now here I am anyway.
I'm 23 now, and when I was around 18 my cousin's mother used to work a lot and my cousin used to come to our house after school.She was around 12. Once we were having a pillow fight in my room and I got tired and sat on my couch for minutes and she jumped on me to make me continue the game but she sat on my genitals area without knowing. I was in puberty and I felt aroused and got an erection. She noticed and sat there for several minutes in silence. Next time, she kinda made me sit on my couch and sat on me again, this time she started touching my genitals for couple of minutes in a way of curiosity. I'm sure she wasn't aware what she was doing. Times after that she started touching my body and hugging me, but I didn't touch her once. This scenario happened for several months and I was liking it in that age and she was liking it as well (or maybe she was just curious). Now after years I feel embarrassed about what we did back then and I feel guilty. Did I take advantage of her? Was she liking it? Did she know what she was doing?
I don't know. I meet my cousin once in a while in family gatherings and she never mentioned anything about it and has never acted weird around me. But I always feel guilty and embarrassed around her. What should I do?

Hello Friend,
It seems as if you both didn't take it too extreme levels. You both were letting hormones get the best of both of you, and the fact that you realize that it was inappropriate is assuring that you aren't a predator. Your cousin had no idea what she was doing mind you. She was only 12, but you are not a abuser or molester for this incident.

Your actions were inappropriate, but you did not seem to have an intent to harm the girl sexually in malice. If your Cousin seems fine now, I would not bother bringing it up unless it is bearing heavy on your conscious. I would not let the guilt destroy you, if your cousin is doing well I would leave it alone.

Best of luck! You didn't do anything extreme. Forgive yourself and live life.
