Hello @meggymoo14 , thanks for sharing your story with us. It sounds like there has been a lot on your mind lately. I imagine that you are feeling quite stuck as you want to ensure that your son is supervised and not having sex yet, but it also sounds like you are very trusting of your son. Have you had a chance to talk with your son and share your concerns that you have around him having sex? I think it is important that you let him know how you are feeling as his reaction might help you feel a bit more at ease. A healthy discussion around safe sex right now might be just what he and his girlfriend need. Although, there is a lot to cover, so it is not always an easy discussion.
I understand that you are concerned as this is a big step in your son's life as it signifies him maturing. It might make you feel a bit better knowing that this is a fairly common experience for both yourself and your son as it has been reported that the average age that Australian teenagers start to have sex is around 15 years old.
If you haven't already, I would recommend that you have a read over some of the articles that we have about teenagers and sex. They cover a lot of various topics aroud sex and can even give you some tips on how to discuss sex with your teenager. If you think it is more helpful chatting with someone about this, you could try calling up some helplines such as Parentline to get some advice from a trained counsellor. Please feel free to keep us upated
