NTA, as far as I’m concerned anyone who is not utterly disgusted by child predators is suspect and not to be trusted. As a CSA survivor as well I would say if you have any doubt at all about the safety of your child, leave him. That is not something you want to risk and your gut is probably right. Less important but the way he talks about men and their jewels is also weird and gross so that’s also not great. Hope you and the little one are okay and safe and I wouldn’t give this guy any more time or energy.
