Is it normal for a 6 year old boy to start having erections?

It is normal for boys of all ages to have erections. Erections can occur for a variety of reasons, including physical stimulation, emotional excitement, and even during sleep. In most cases, erections in young boys are not a cause for concern and do not require treatment. However, if you are concerned about your son's erections, it is always a good idea to talk to your doctor.
