It depends what you mean by sex education.
Sex education is not a one size fits all thing......and sometimes it will stimulate a curiousity to try out the things which have been discussed.
I think it would be far better coming from parents(they are best able to respond to questions in an environment that is familiar and the child need not fear being ridiculed by peers)...and that children should be told about inappropriate touching of parts covered by a swimsuit.
Children should be educated to know to tell a parent if there has been any inappropriate contact by anyone......even if that someone is a teacher, a family friend or another family member.
