Please Help Me Doc..i Got Serious Problem

i am 21 years old and still studying. i am 6ft 7in tall and 113lb.

i got body odor problem which i noticed it since i was 15 years old. i had been told by my friends since i couldn't smell my odor myself. this problem is really killing me.

i have tried a lot of method to encounter it but it still come to zero. from the hygienic view, i am good at it since i noticed i have body odor. i have 3 times bath (5-7 minutes each bath) daily but still cannot overcome this problem. i use deodorant and other antiperspirants to help me but still it come to zero. the problem is this odor is not focusing at my underarm but my back which is much more inhibit bacteria compared to my underarm. sometimes my underarm smelly too but i can overcome it using deodorant.

my confidential level has decrease as i in the public situation since i knew i have this problem. but i am confused about is this body odor problem because it happened when i started learn how to masturbate. i start this masturbate habit since i was 15 years old and two years later i stopped it and the body odor gone away. when i was 18 years old, i started that habit again even though not as much as i was 15 years old. usually i do it once a week and i am continuing body odor problem. if i stop this habit for about two month i can overcome this problem but what happen when i am married one day?. i can't having once sex relationship in two month.

is there any solution that you can suggest ?. is there any problem with my kidney or liver?. i think i got internal problem which might caused body odor to me. is there any supplement or medication method to overcome this problem?. since i am a student, i hope those solutions you give to me can be afforded by a student. please help me because this problem can kill my life and my career one day. -troubled-
