hello,im an underage boy,ive been m*st*rbat*ng ever since i was 12 and i have took a month or week breaks sometimes and i beg for forgiveness 7 times a day.I have a important exam coming up in a month and i want to stop for a better result. is it a sin for me??? i always believed that at any day i havent m*st*rb*ted,i have a clearer mind and get better results so i NEED to stop but i also wonder if its a minor or a major sin for me
