Occasional stinging post ejaculation

Once in a while I'll end up with a stinging sensation in my urethra after ejaculation. Seems to be more likely to happen after masturbation, but sometimes from intercourse. Only happens rarely and tends to pass after 20 minutes or so. (Don't tell me its an STI either, its not)

What do you use for a lube during masturbation? I learned as a teen not to use soap slime to lube up with. It can get into the end of the penis and burn. If your stinging gets more frequent, see a urologist; may have prostatitis, inflamed urethra.

A few years ago, I noticed what looked like old, red-brown blood strings in my semen and I had a little burning. My FP Dr. checked my pre-cum under microscope and found dead blood cells. He put me on Bactrim tabs for a week and all has been fine since that.

I learned that same painful lesson with soap as a teenager too, that's just bad news. I'll either just use my own precum(I produce a bit of that) or a water based jelly. Occasionally it happens from PiV intercourse too.

Oh certainly will. It's not really that often and it passes within 20 minutes.

Yeah I've never noticed anything like that with my semen. My semen looks the same as usual when this happens. Maybe I'm just somehow mechanically irritating my urethra?
