Hypersensitive glans and weaker erections

Hello

I had a phimosis until the age of 22.
I went to the hospital for a small surgery to be able to pull the foreskin fully.
I can uncover my glans even while erect but it still feels like my foreskin is a bit too tight. I will try some extenders later on.

But the point of my post is that my gland is so sensitive that it actually hurts whenever I touch it in the shower for example. Nothing can touch it without me feeling pain.
Even the foreskin hurts when it is pulled, you can see the under side of the foreskin, right ? Well if I touch it it hurts like hell.
As if someone kicked you in the groin with his foot.

Whenever I was fapping even after the surgery, I was still keeping the foreskin completely on the glans, because:
1. It is still tight, so if I retract it fully behind the glans it will stay stuck behind until I push it back (I really have to push the skin).
2. The glans and the under skin of the foreskin are hypersensitive.

Never had sexual experience because I'm too scared of those pains.

Even though I have been masturbating and edging for years 2 to 4 hours everyday.

Do you think my weak erections are due to:
Post surgery psychological effects ?
Or
Tired dopamine receptors and over fapping habits ?

I have an appointment with a sexual therapist (sexologue) in 15 days and I keep doing the no PMO like a monk for now a month.

Nightly erections are strong and frequent.

 

My foreskin was all my life covering my glans. I touched my gland maybe a hundreds times in my whole life.

I'm this case, is it normal my glans is so sensitive whenever I touch it, even a fat drop in the shower does not feel comfortable at all and I move back.

I need a lot of courage to actually touch it and rub it just to make it less sensitive.

Do you think it will get less sensitive if I do so ?

 

Another question

Do you think that pulling the foreskin and leaving my glans in contact of my underwear all day can reduce this pain feeling and make it enjoyable when my partner touches it ?

Also, do you think it would slower my recovery with fixing my erections ?
