the last line of this is “My name is Ye and I ****** my cousin’s ****** till I was 14
so from this we can assume he was at least younger than this. No more information than that or how longer it went on for but we are not talking about an adult and a very young child. Of course there is no way to tell what the age difference is between them i Will caveat this y saying if there was even a couple of year differences between their ages then that borders away from young children experimenting to an older child (who I’m not saying is the same an adult) to an older child groom another.
I feel very sorry for his cousin who I assume has had no choice in this information coming out which is bad enough but if he is still in prison this will put him in danger
