Hi. I am 36. I've been abstaining for a few months due to my wife's pregnancy since last September. Around August last year, I'd passed a nearly 3mm stone. Since abstaining I began to have some mild burning sensation. Often there would be whitish fluid stuck to my underwear. I went to a urologist who asked me to masturbate. I have been doing that since December. But I have noticed that more than often my semen has a yellowish tinge to it. Once it falls in the commode it becomes slightly yellow. The other day I dropped it on my palm and it seemed colourless. Is there something wrong with my semen? I have no other symptoms. The smell is like usual semen smell. I did tell my urologist who did not seem to be bothered at all. Please let me know. Thanks
