text: i produce semen daily is it harmful.does it affect my reproduction capacity?   not really;but it affects ur overall health.constant ejaculation of semen is not a healthy practise. to ejaculate, u definitely need an long-lasting erection,which enlongates ur wee-wee but sometimes extremely painful if it lasts over 4hrs....just quit masturbating or taking viagara daily.channel ur energy  somewhere else.
