I bought my son an escort for his fifteenth birthday
He's underage, why do you think it's appropriate for you to hire an escort?
I told him not to tell me about his night with her. I'm curious how was it between them
You shouldn't be hiring escorts especially for people under age. That was really wrong what you did.
What did I do wrong? I wasn't with them.
It was even worse for you to not be there as you left a minor with an adult person that is a stranger to him, and he could have been badly hurt or traumatized with the experience. It's very weird enough for a family member to hire an escort for another family member, so I suggest you do not do this ever again, and let your son have his own sexual activities private.
