My DNA can change because of ingesting other man saliva/urine?

Hi there, i am 35 male from London. If i ingest saliva/urine from other man, will my DNA change? Will my future babies will have trace of the other man ?

No, it is not possible for you to change your DNA in any way.  If it were easy to change a person's DNA, then gene therapy for diseases would be a breeze.  As it is, even under the most ideal, lab-controlled situations, it is very difficult to get human cells to incorporate foreign DNA, rather than rejecting it.  You would never be able to do it accidentally.

Think of it this way - when a woman is pregnant with a male fetus, there is all sorts of DNA mingling, but nothing ever comes of it.
