I can not streach

Every time I do after about 5 seconds it starts to fill up with blood,
And by the time I hit 15 seconds I’m at about 60 to 70- % erect

This happened 3 years ago as well when I was 17

I can’t be the only one this happens too or has trouble with

Stopped after a few weeks, lol
Now I’m board and looking around.

Try not to grip so hard. Focus more on the pull.

Ease into your stretches. Don’t start them at a full-on 100% yank.

Your dick is trying to learn, give it some time.

Normally and up to now when ever you touched yourself it was for pleasure and your dick/brain understands that. Now you are trying to do exercises and it doesn’t understand the difference yet. Stretch, when it gets erect let go until it goes down, rinse repeat. Your dick will learn the difference and will react differently.

sunny’s advice is spot on, but your other option is to masturbate before doing PE. It isn’t the ideal, but it can help while your penis is ‘learning’.

Just do some forceful dry jelqs until the erection fades.

I had the same problem when I first started. It’s because you are doing something to your penis you don’t usually do. So it arouses you a little. But you will get used to it and it will get easier to get a good stretch instead of an engorged horrible stretch!

Ok apply these two techniques simultaneously and probably you will overcome the problem.

1) Think of something ultra un-attractive or something totally irrelevant with sex, girls etc etc
2) Do it while standing and bend one knee so that you have most of your weight on it, exercising your quadriceps. By performing any physical exercise and getting tired will make your erection go off.

What? :/
