7 year old touching and initiating sexual behavior with 3 year old

[danimom07]

My little boy is 3 years old and looks up to his 7 year old first cousin. They play together a lot of the time. Lately the 7 year old has been offering to take my little boy to the bathroom and "help" him do many things. I also have a demanding 18 month old. I allowed my little boy to get help from his cousin. I regret this and feeling upset at this situation. They were in the bathroom together the other day and maybe 5 minutes went by. To make a long story short I realized they were in there too long together and by that time they were coming out. They began sneaking around and whispering and the 7 yr old was telling my little boy to go to areas of the house where I was not. I kept following them and I walked into the play area, in a corner, my nephew's penis was hard and he was telling my little boy to take his pants down. My nephew also admitted that he stuck his finger to my little boy's anus, and he made him do the same to him. This came out after repeated different "stories". Also my son told me parts of it. Is this normal? I am feeling this is not and and very worried my nephew has been doing things to my son for awhile! I just cannot let my mind rest. I separated them. I don't want my little boy to play with my nephew anymore! Is this too strict? What should I do?

You should definitely keep them separate. Nothing is too strict when you're protecting your little boy. Sure, kids do some sexual exploring, but no 3-year-old should be exposed to such behavior! Your nephew might need some help too.
