If there is sperm or semen left in the penis or the vagina after sex it can wash out later with your urine. This is no problem at all and perfectly natural.
Urine and Sperm
Normally sperm is white and a bit thicker than urine. If it is clear and thin it is usually because you haven't hit puberty or you havent had sex before. Do not worry all you need to do is masturbate regularly and overtime you should produce sperm.
No, normal urine does not contain sperm. If there was sperm in the toilet then it would still be impossible for the woman to get pregnant in this way as humans require internal fertilisation
Sperm naturally clots even if not mixed with urine. The sperm clots in order to help make a "plug" so it doesn't come out of the vagina before some of the other sperm can have a chance to fertilize the egg.
