when i ejaculate its all fine until the end when the seamen coming out starts to turn a reddish colour. this has happened before and i decided to go to the doctor and i got it all checked out, doctors checking if my tesicles were fine, ultrasound etc. but they couldnt find anything wrong and the bloody seamen eventually just stopped so i forgot about the doctors. now its started up again and i dont want to go to the doctors cause they waste my time and i face up to the embarisment and they dont tell me whats wrong. so hopefully someone could tell me why this could be happening? its just really annoying and i just wanna know why its happening. thanks.
