 [ Symptoms ] 21 years old masturbate 1 2 times a day regularly had a possible uti now ejaculating less retrograde ejaculation  i would pee then a while after masturbate and after ejaculation it felt the inside of my urethra was burning peeing more helped but only temporarily burning went away in 15 30 minutes happened 3 4 times in one week then went away now basically overnight i am ejaculating far less had a head cold mucus in nosethroat throat swelling does being sick effect volume  i am taking zinc and a multivitamin equals 35mg of zinc and dietary supplement witch hazel bilberry horse chestnut [ Disease ] lay off for a few days and i am sure your volume will return most ejaculate is semen not sperm created in the prostate gland twice a day can be a bit much for this overworked gland to recover if you are still having burning you will need to see your medical provider but as a man it is not very likely that you have a uti but you could have prostatitis this is just a guess however since making that call requires an examination your cold has nothing to do with this issue
