23 as well (why are most men here 23??)
I'm sitting here, on my smartphone, at the end of the line, and felt the need to contribute.
Same thing here: drink alcohol, ejaculated (sex, but has happened with masturbation as well), and then pee. No itchiness ... Just pain. Pure pain in my penis. It is terrible! But reading about all of you suffering makes me fee better :)
So the cranberry juice tip above is solid advice, I've done that before. But if you don't have cranberry juice, drink water instead. You want to make yourself have to pee, that will help the pain go away. Keep drinking that water!
On a side note, I've been trying to find any form of instant pain relief ... Because, as some of you know, this can really hurt like a b***h and any form of instant pain relief would be so helpful. Well, I decided to turn on a heating pad (highest heat setting) and press it against my crotch. It doesn't really make the pain go away, but it makes it slightly more bearable.
Hope this helps.
HOW DO I MAKE IT STOP IT HURTS
For me a hot shower is the only solution I've found. I stay in for the majority of the pain with the hot water all around my penis. This soothes it, but doesn't eliminate it. I also will sit on the toilet and do something on my iPad to distract me like typing this so I can pee when it hurts. It sucks, I feel your pain.
