Dear Senaka,
It appears that your son is having retractile testis which may be quite normal for his age.  However we should be sure, that we are dealing with retractile and not undescended testis, which have very different management implications.  Most testes usually don't descent after 1 year. Therefore if there is a slightest doubt as to what are we dealing with, you should arrange for an appointment with a pediatric urologist.  He will examine and make sure that the testes are descended normally.
