Sometimes have Pre ej, sometimes not?

[Toky]

So I had in my life once pre ej, that I could not have sex for half minute, but handjob I could have for half an hour (by girl). I cured that, and now sometimes I have pre ej, sometimes not. There is time I can have sex like a pornstar for 20-45minutes and there is time I struggle to last 5 minutes. Why is that happening?
Also I must mention that if I have like 3-5 sex where I edge and try not to cum fast I gain more stamina (can last longer in next sessions) and then if I mastrubate on porn I lose all my stamina.

Anyone help please?

Tryi to remember the time you last 20-45min and compare to that day you last only 5min. What is the different you did during sex? Before sex? The day, whole week or whole month before that specific intercourse and compare the difference of them.

Different between
Physical: work out? Or Sitting alot? Anterior pelvic tilt?
Mental: stress? Anxiety? Deppression?

Et cetera...

I think that when I'm thinking about sex and it's outcome before it I perform alot worse. Also I think that mastrubating on porn even once give me PRE ej

How did you masturbate? Tight grip or light grip?

Has there any others difference between succesful and "failed" intercourse. Tryi to remember everything.

Always light grip mastrubation.
Hmm I am very aroused when I "fail", also I can't get it out from my head that I won't last longer, I am too sensitive down, even little bit scared

Many member with pre e have masturbated with light grip. One of member who had delayed ejaculation and sometimes unability to ejaculate at all told that his doctor told him to masturbate with light grip. And it cure his delayed ejaculation.

Are there any other difference on that day or weeks before intercourse between succesful and failed intercourse? You can write here everything. Did you eat something different? New hobby? It doesnt neccessary need to logically related to your penis and pre e.
