Parents are happier to talk about sex (or HIV) when they feel prepared and know what to say. As with disclosure, you should prepare yourself before beginning conversations with your child. The Family Planning Association have made lots of resources, and even have a parent’s pack you can buy to help you talk to your child about sex.
Remember, this is not about expecting your child to start having sex, but helping them prepare well for when they do. Research shows that these conversations lead to young people having sex later, not earlier.
There are many places online where you can read about other parent’s experiences with teenagers and forums where you can post your own comments or questions. Websites such as Parenting and Parent’s Chat offer both advice and forums. Have a look at a few and decide which ones may work for you.
For talking to younger children about sex and puberty and older ones about sex and relationships there are many books and leaflets available. Have a look around and find the ones you like and feel comfortable with. You could try the FPA or Leeds Sexual Health.
