Ok thank you so much grace, im really glad you guys are here to help. I was starting to get a bit worried there for a moment.
I'm guessing it's the irritation of you masturbating. buy yourself a decent lube like ky or astroglide and use it when masturbating and see if that helps.
I think you are over thinking this far too much to be honest. you have bacteria on your hands and your genitals and masturbation rubs that into your urethra as well as rubbing your urethra irritates it.no, it's not a bladder infection since it only occurs sporadically - if it was a bladder infection or an uti, you'd have constant pain and far more symptoms. since you have pain, sounds like you are paying too much attention when you urinate afterwards to notice the color of your urine. in general, drinking several glasses of fluids a day is best for your body to keep it flushed out. if you aren't doing so, start!

well it only happens after pleasure after I urinate the first time, the urine seems to be yellow and irritates the tube and tip, would this be bladder infection or something else worse. I am kinda lazy when it comes to eating properly and drinking alot of water or nutritious fluids could this possibly be a cause of the symptom? Or would this be something STD related?
No none whatsoever, Could it be a lack of water? Cause I also notice anytime this happens the urine is always a mid to dark yellow never any weird colors or anything.
odds are this isn't std related since it only happens when you masturbate.
do you use a good lube when you masturbate?

Also during that 1hr pee spree the middle of the penis where the pee flows about midspot gets irritated.
