Should I be worried?

I have been dating my boyfriend for about 9 months now. He’s got a 4 year old daughter whom he has custody of and an 8 year old son whom he has joint custody of. I have two kids, my girl is 7 and my son will be 6 in a few weeks.

I just found out recently that about 5 months ago, my boyfriends 8 year old son exposed himself to my two children and his sister, and then insisted that my 5 year old son kiss his privates and “lick his ass”. When my son refused, the 8 year old boy tried forcing my son to do it by shoving his head down.

I did not know about this mind you till just recently.

We went camping twice last month. Our second time out my children when alone with me told me that the 8 year old boy pulled down his pants and again wanted my 5 year old son to kiss his privates. Then he asked my daughter to pull her pants down. She refused, as did my son, but aparently his 4 year old sister pulled her pants down. While they were supposed to be going to sleep in the tent.

My daughter also told me that the 8 year old boy went into the bathroom with her while we were camping and peeked in the stall at her while she was going and also pushed the door open while my son was going to the bathroom.

I told my boyfriend about the camping incident right after my kids told me. He took his son aside and had a private talk with him. His son denied everything. We then talked to them altogether and made sure they knew what privates meant and that it was theirs and theirs alone.

This boy still denied it. Which upsets me greatly. Since then after a few conversations just between my kids and I, I have told them that if anything inappropriate goes on with this kid or anyone else to tell me.

I am worried. I have talked to my boyfriend about it, and he has asked the boys mother if anything is going on at home with her or her boyfriend. She says no. My boyfriend has left it at that, and a few intense conversations with his son.

Honestly it worries me having this boy around my children. I am not sure if I should consider him a potential predator or not.
