Whats an easy way to tell my dad about my boyfriend?

if he is truly your boy friend, not hesistate to say he is my boy friend. but you have any guilty mind and both (you and your friend) do the activities not accepted by any parents and surroundings then one is accepted as you are friends and you now 13 years old therefore concentrate on studies and be a good daughter and good student. 13 to 20 years is girls and boys physically and mentally changing age. therefore love, affection . . . . common therefore control your mind and avoid all these things and do your work. day by day you will be know what is friendship, what is relation and so on. parents are very tensed regarding their childrens future dont give trouble to them. i hope you will under stand my opinion and follow the lines.
