Be Honest With Information
Both teenage girls and boys go through a period of physical and emotional awkwardness.
At this stage, girls need to have menstrual cycles, hair growth in the armpits and pubic area, the widening of their hips and the change in the pigmentation of the skin all explained to them.

Boys need to be spoken to about the changes in their voices, about nocturnal emissions, which they will know as ‘wet dreams’, and the rapid development of their sexual organs.

Get them a good book on sex education, which can be read in private. Back it up, if you can, with casual chats that do not appear to have been engineered. Deliver the information in small, well-spaced and timed discussions rather than in one big solemn lecture.

It is perfectly normal to feel uncomfortable about it all, but considering the options (sleazy films, cheap porno books, uninformed friends, and porn on the Internet) might help you quickly get over the discomfort. But if you just cannot bring yourself to do this, enlist the help of another adult — someone too young to be seen as a parent figure but old enough to know what to say. It is also absolutely necessary for youngsters to be made aware of the hazards of unprotected sex — pregnancy and sexually transmitted diseases,including the dreaded AIDS.

Explain to your kids that delaying sexual relations till they are mature enough and sure of their feelings for their partner, is definitely a good idea and that it, in no way, undermines their sexual identity.
