Tip of penis not getting hard?

Hi so I’m trying to recover from pmo and not using lube when masturbating. I am loads better now, was even healed at one point through meditation, but old habits came back. I’m getting really strong erections it’s just nothing happens in the head of the penis anymore. I can get it to go hard and it will last about 5 seconds before going back down which can kill the rest of the erection.
Does anyone know any solutions please and why it’s only the head playing up now

 

I’m a young fit lad who plays lots of sports, this shouldn’t be a problem

 

What’s the situation with you, what helps and makes it worse?

 

I’m trying certain foods that are supposed to help and a big change I’m making is not drinking from plastic bottles, I’ve bought a chilly stainless steel one. The plastic bottles can increase the amount of oestrogen in you which I imagine kills sex drive. This is where Alex Jones got his ‘the waters turning the frogs gay’ thing from

But yes for diet I already eat tons of chicken veg, tuna, never fast food etc. I’m a fitness freak. Apparently spinach is excellent for erections, I’d recommend organic and chemically sprayed ones can cause others health effects. I got mine from Tesco, coffee or green tea are supposed to be good too!

 

Yeah I’m doing my best, it’s like once every 3-6 days and I’ve started using lube going a bit slower
