1) I'll try to drink that quantity, okay!
2) I always make sure to clean it. The pain comes too even if i do it in the shower, so it shouldn't be a cleaning problem. The foreskin is a little bit irritated and a little bit more.."sore"(?) like more thick (not hard tho, just thick like if it had water in it). But my hands gives 0 reaction to semen.
If it's the semen that's making this effect, it has to be the one remaining inside (if that happens by "mistake")
I'll try to drink more water from now on. Btw, could an infection be the cause?
Btw, sometimes the pain is still there without erection. I notice that if I've gone for a walk or something (before those 8h). The pain is really unbearable even in this flacid state (pain level = making painful faces) (i don't really know how to quantify pain).
I think Biomajor has done a great job of narrowing down the possible causes of this pain.
My thoughts are that it is not a semen allergy. It doesn't fit your symptoms. What does fit is your prostate. There are muscles in the prostate that force semen out and into your urethra.
You aren't doing anything to obstruct your urethra are you? Some guys do block the end to try to shoot further.
The prostate also serves as a "valve" to either urinate or ejaculate and you can have some "difficulty" urinating while the transition is taking place.
It may be that you could have a form of prostatitis. It is very common and often more common in uncircumcised males.
I'd suggest a visit to a urologist for an evaluation.
Hope it helps.
I'm not actively doing anything to force that :/ Maybe by mistake but i never tried to block it (I will pay extra care next times).
I always thought that prostate problems are more of an "adult" thing and never really considered it. One of the times i was looking for info, I read something about that "valve" thing, and i noticed that I have no problem urinating when erect and/or close to ejaculation... does that mean my valve isn't working correctly?
In response to both of you, going to a doctor was my next step. It's been long since i've gone to a doctor, both my parents have studied medicine so i barely visit specialists. But seeing that this problem has gone for many years and it's really starting to affect me, i'm sure i have to arrange a meeting with one. Let's see how i can make it without my parents really noticing; i know it's stupid but i don't really want to talk about this with them.
Btw Biomajor, yesterday i tried to drink 1500ml of water..That's a huge quantity :/ I spent the day going to pee transparent urine, but i'll try to keep this 'water diet'.
PD: It is difficult to treat prostatitis?
The "valve" thing is just part of what the prostate does. It's a muscular organ. It can hurt like any other muscle. You say you edge, that can increase the workload for the prostate. It's getting ready for an ejaculation.
You could have a slight infection. Not being circumcised does increase the risk. Antibiotics are the usual treatment.
