can get a boner but problems with having sex ->PIED?

Hey everybody,

I am 28 yo and not the type of a shy guy. I think a look attractive to woman and had some relationships in the past. It is no porblem for me to get in contact with girls.

I MO since I am probably 13 yo and even watch porn this long.
About 5-7 times a week.
In the last couple of years I can't remember waking up to a totally full erection.


My issue:

when i met girls I can get a boner easily from kissing and touching.
But when it comes to sex after a short time I am not hard enough to penetrate her.
This happens not all of the time but meanwhile I am afraid of sexual contact. Sometimes I cannot be hard all the time if she gets me a bj but a hj works well.
With my last relationships the sex was sometimes very good but on the other hand it doesn't work that good.

Sometimes I tried not to musturbate before meeting my ex/some other girls to be even harder. That turns out quiete good but not everytime. I often watched porn and M but not to O. I just stopped before. My erection is even harder and more easily to get if i watch porn.

I wanted to go to a doctor that I can be sure everything is good down there.
I have questions in my head like: Is my dick too long to be complete hard or why this happens to me most of the time?

Than I heard of nofap, read some articles and finally found this amazing forum.
I heard the first time that PIED is a real problem caused of the f***** porn industry.

My plans:

I want to go for a 60 days challenge of no PMO. But stop watching porn forever.
In my opinion it is okay for me to have sex with girls but in the next 2 months I will avoid it. An other point I read in the forum here is that it can be very bad if I always M with a hard grip and than at sexual contact the grip is less lighter.

You are a really great community if you have any questions feel free to ask me

I will share my progress and results with you out there...
