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.
21 years old masturbate 1-2 times a day regularly. had a possible uti now ejaculating less. retrograde ejaculation? . i'd 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'm ejaculating far less. had a head cold (mucus in nose/throat throat swelling). does being sick effect volume? . i'm taking zinc and a multivitamin (equals 35mg of zinc) and dietary supplement (witch hazel bilberry horse chestnut).
