It's not a good idea for YOU to have contact with children right now. But many BLs and GLs have learned to put their sexual urges in the right place and aren't bothered by them while interacting with children. Many BLs and GLs can trust themselves around children. As you learn to accept yourself and understand yourself better, this may become true for you in the future. If that day comes, then it may be acceptable for you to spend time with children at that point. If it doesn't, then it may never be a good idea for you to be around children.
