Random erections

Hello, friends!
I am successfully doing the PMO challenge and I didn't have any major issues or cravings until a few days ago. My problem is that I constantly get random erections at about a 4 hour interval...
I can be on the street, at work or at home and "POP" my Timmy wants to feel the breeze!
I am 37 so it doesn't have anything to do with puberty or hormones.
I am worried that when I walk, there is friction between my clothes and my penis, which can create pleasure and I don't want to cheat on the challenge and worsen my condition.
I admit that in the past I was moderately active and I am/was bisexual (I hope there is no discrimination here).
I heard that masturbation and porn can cause ED, which I desperately want. But I tried it for years and it didn't work. So I decided to take the inverse approach with the PMO challenge and it worked for some time, until now.
What should I do now?
Thank you for your time!

 

The four hours interval is more like an average. Sometimes I get more often sometime less often.
I get erection when I am home and not wearing any clothes so friction wouldn't apply in that case.
I am not quite sure what should I write in the journal because I don't feel a psychological carving, it is something purely physical, if you know what I mean. Suddenly I just feel a pulsation and a pressure that doesn't go away for a few minutes.
I will go to the doctor.
Thank you for the advice!

 

I didn't want to give personal information and I thought being younger would make me more relatable.
Thank you for the advice!

 

I desire to achieve total abstinence and not being able to do it is much easier than constantly suppressing it. I would give you my condition if I could!
I even considered castration, but unfortunately it has negative effects on your health and quality of life...

 

Yes, it certainly is an extreme solution, but I am not in a situation with a lot of options and if my sexual desire acts up(which it probably will) I will be in an even worse state... For me, everything will be a trigger...

 

There are plenty of people out there who can offer a lot more than I ever could so no one is going to miss me. It is an interesting perspective, thou!
Thank you for your comment!

 

I tried this method, but for some reason it doesn't seem to work for me...
Thank you for your advice, thou!
