75 days no morning wood ?

Hello so I am new to this website I usually post on reddit but this seems more nofap oriented even more than the subreddit.

I am 20 years old and I have been watching porn and masturbating since i was 12. At 19 is when I started cutting back in porn and masturbation. But still did it about 4 times a week sometimes more.

I am loving nofap and ill never go back but I'm worrying why my morning wood is nonexistent still. I've had about 5 morning wood from day 0 to day 75 which is a very small amount. I've had about 4 wet dreams.

I'm worried should I keep waiting possibly to day 120? Because I know day 90 isn't always the last day people become fully cured. The reason why I'm worried is because could I be testosterone deficient? I've asked my doctors if they can check my blood for that but they don't believe I can be since I am so young. I dont know what to believe since I know it could be from all the years of pmo.

Any one with experience?
