Im scares of my son being around men who seem gay or been in jail a long time?

So my older cousin just got outta jail and he seems a little.different. He just kinda scare me like he may be attracted to little children. I dont know if im over reacting but im also scared to leave my baby around my nephew who is only 11. He acts a little gay and pervertic. Idk but I hate thinking about this when either of them are around or people like them.when I was younger I was fondled w so I guess im just remembering from then and what it did 2 me deep inside. Anyone do yu have any insight?
