Emotional relationship symptoms and conditions

IM ONLY 19 MY SEX DRIVE IS AT 0. THIS IS DEF NOT NORMAL FOR ME. MY BOYFRIEND OF 2 YEARS AND I NEVER HAVE SEX AND ITS BECAUSE I NEVER FEEL LIKE IT I JUST DON'T HAVE THE DRIVE WHEN WE USE TO HAVE SEX AT LEAST 5 TIMES A WEEK NOW ITS ONCE EVERY 2 WEEKS AND ITS BECAUSE I FEEL HORRIBLE FOR NOT GETTING TURNED ON. MY BOYFRIEND THINKS IM NO LONGER INTO HIM AND IT DOESN'T HELP THAT HE HAS AN INCREASED SEX DRIVE FROM WORKING OUT AND BEING A FIREFIGHTER. THIS WAS NOT THE CASE BEFORE YAZ I THOUGHT IT WOULD HELP WITH CRAMPS AND ACNE BUT ID RATHER HAVE THOSE SYMPTOMS THEN NOT HAVE SEX WITH THE PERSON I LOVE.NOT ONLY HAS IT EFFECTED OUR SEX BUT NOW OUR EMOTIONAL RELATIONSHIP SINCE THIS HAS BEEN GOING ON FOR ABOUT 5 MONTHS IM A REALLY BUSY INDEPENDENT PERSON WORK FULL TIME AT A HOSPITAL AND GO TO SCHOOL PART TIME I JUST NEVER HAD THE TIME TO BE TOO CONCERNED HONESTLY I THOUGHT IT WAS JUST A PHASE BUT MY BOYFRIEND THE OTHER DAY SAT ME DOWN AND SAID IT HAS EFFECTED HIM JUST AS MUCH ME IF NOT MORE BECAUSE EVERY TIME I TURN HIM DOWN IT HURTS HIM ESPECIALLY SINCE HE KEEPS TRYING AND IS NOW EXPECTING ME TO SAY NO AND I FINALLY REALIZED THIS IS A HUGE PROBLEM AND IS EFFECTING ME MORE THEN I REALIZED. IV MADE AN APT TO SEE MY DOCTOR I THOUGHT SOMETHING WAS WRONG WITH ME UNTIL I READ THIS AND NOW IT GIVES ME HOPE TO MAYBE ITS JUST YAZ. THANKS TO ALL WHO SHARED
