Problems with erection

I have been PEing for little over three months and my results are very pleasing (went from 6 inches to almost 7) and although my erections are better, the same problem occurs always.. When I have sex or even when I use flashlight alone (so no stress), during the penetration my penis gets to around 70% of erection which is still enough to have sex but all the results I got from PE are nonexistent because not fully engored penis is smaller and most importantly thinner. I use a ring and although it helps, it is still.. Fuck I don’t know.
I have 93 kilos and with my height I should lost probably 15 kilograms to be ‘healthy’ but still.. I had this problems even when I was doing sports, eating healthy and had 70 kilos.
Something is wrong here and I suspect venous leak because when I squeeze my glans it automatically starts loosing blood and becomes soft.. And it is also better when I am sitting than lying.. But I had no injury, nothing hurts me and most of all, I have this since I was teenager, as long as I remember.

It is fucking frustrating and I don’t know what to do.

Tell us about your masturbation and porn habits.

Well, I am watching porn once a day and it is only because I am jelqing 4 or 5 times a week and I need some stimulants to get it up to about 70%.If I didn’t have porn it would be impossible I guess.
I masturbate after jelqing and then on my free days because I am training to last longer (I put flashlight foam to hot water and then try to last as long as possible)..

I am aware that I should cut on porn and masturbation but I need porn for jelqing and I need masturbation for lasting longer as I currently last only about 5 minutes.. Which in combination with the fact that I have EP is a fuckin bummer.
However, if you have any recommendation or tips how to avoid porn and masturbation so often let me know :) I am opened to change

Get a hobby

Stop watching porn and stop masturbation. I think that’s the best way to get better erections. Why don’t edge instead, without porn? Isn’t edging a good way to learn not to cum and it will get you better erections as well.
How old are you?

Edging is not effective in bed.. I don’t think a lady would be happy if I just started squeezing my dick every other minute. And when I am training alone it is after all better to learn to withstand the heat if you know what I mean..

Anyway, I am 23.

I ment edging alone, almost reaching climax and stop.
Doing that over and over again is a way to learn how to last longer. And if you don’t cum after a session like that you are likely to get harder when it’s time for the real stuff. But I guess it takes som time to master. I don’t know, newer had these problems. If I feel that I’m about to blow I just slow down and let it pass.
