6 yr old boys playing with other 6 yr old boys

I have a 6 yr old who at the age of 3 was confronted by a friends 5 yr old about playing "let's take your pants down" I advised the young man that this is not acceptable and sent him home. To find out a few years later that my son isn't the only one he has tried this with. My Husband and I talked to my son, and we hadn't had any problems since. Later that summer with my neice and son and they are a couple years apart (She's older) I found my neices hand down his pants. I spoke to her mom about it and she said it's there age.  Then this past summer my 6 yr old and 3 year old were playing with my 3 yr olds friend and I was in the living room with them I went into the next room for a total of 2 min when I came back my 6 yr old was behind the couch with my sons friend (age 4) when i confronted him about what was going on he said they were playing and were looking at each others personal areas.  I again told him this isn't acceptable and he apppologied.  I Spoke with my friend and let her know what happened. She said not to worry about it because it's their age. ( She has older boy). Last week my son and his friend the same age went out with me and they both wanted to go to the bathroom together. I didn't think anything of it, then 3 nights ago this same friend was at my house, My husband and I went out to our front porch to speak with a neighbor when I came into the house the "friend" said I have to go to the potty, then I noticed my touching his private area saying it was itching and that's why he was touching it. I didn't believe him so I made him talk to my husband in another room. When the friend came down from the potty he wanted to go with my son, I told him he had to stay with me.  When my husband and son returned to the room with me the friend said he lied  when I asked about what he said I can't remember.  Then the kids went outside and the friend pushed my son and said why did you tell? My son came straight to me and told. When I sat with my son later that evening and talked about what happened he said he touched me and Put my hand on his personal area. When I asked why he didn't tell me he said he was afraid he'd get in trouble. I again let the mother of this child know what happened and again was told it is their age. I am not comfortable with this answer.. Please tell me when does it stop?? How do we make it stop? I don't allow him to have friends over because I am afraid it's going to continue. Is he going to end up gay or emotionally unstable? I am a first time mom of boys we haven't had boys in our family in 36 yrs and When I ask my Mother in law if he remembers if my husband went through this she said she doesn't remember.. What can I do? Should I get him counciling and where do I go to get it???

I have one answer keep them apart or supervise more, there seems to be so much of it, so be aware and be around,perhaps find new friends for your son as this child sounds like the instigator.it will continue other wise, and one day someone wont like it and it will be investigated ,children copy . Good luck
