My sperm is normally thick and a white-yellowish colour, but in the last 2 days it has changed. It is now extremley runny & completely yellow. The first time i noticed this i had not had sex for a week so i don't think the runnyness was from alot of sexual activity.
have you considered gonnoreah or clamydia? my friend and i are looking on the internet now for the symptoms, and yours seem to fit the bill. we recomend you get checked for sti's. go find you local GUM clinic.
