Most probable diagnosis in your case is Calcified Sebaceous cysts.They occur where hairs are present.
Nothing to worry.Its a very minor case.
This condition has no relation to sex.You can tell about the scrotal lesions to your parents.
If at all its a Calcified sebaceous cyst,there is no permanent treatment.The scrotal tissue has to be excised if the lesions become large,multiple and not falling spontaneously.
But,please consult your Dermatologist/General surgeon
and take opinion
All the best
