Issues with penis and ED

Okay so for the past 2 months i have been feeling very weird.

I have been masterbaiting almost on a daily basis since i was 14.

I am currently 23 and this is happening.

I couldnt get an erection for like 3 weeks. Then i tried watching porn and focusing and if i forced it etc... i could get an erection.

After sometime i realized it wasnt really ED. In the morning i still had a boner , and now days if i watch porn it does erect kinda....

My real problem is that i cant feel the top of my penis anymore.... Like i have no more sensation as before.

Also i feel like im cumming less..... I have a numbness or like weird feeling on my right testicles , specially around it not the testicle itself.

When i used to masterbait i could tell exactly when i was about to release semen.. Now i kinda can aswell BUT i dont feel it anymore... 

I also feel like its warm inside me.....

The other thing i noticed , is my sleep has changed. I used to sleep 9-10 hours a night.

If i went to bed at 3 am , i would wake up at 12-1 pm.

if i went to bed at 10 pm i would wake up around 9 am..

Now if i go to bed at like WHEN EVER , i only sleep 4-5 hours then cant sleep anymore...

I paid close attention and i think its something to do with my bladder feeling up and it signals my brain to wake up? not sure exactly why i cant sleep anymore.

so last week i went to doctors and did a blood test. they did every TEST POSSIBLE.

from diabetes , sugar , testosterome , teroid , STD's , everything they said its good and healthy.

no liver or kidney issues either.

So whats going on? please if u have questions post and ill let u know...

like i dont get a hard on anymore.. i lost the sensation
