The answer would be pubic hair. Because, secondary sexual characteristics.
Visible secondary sex characteristics are nonreporductive sexual characteristics.
For males things that will start to show are pubic hair, facial hair, and Adam's apple.
It may help if you and your partner still hold that trust and bond you had created with one another and as married you tend to trust each other more and be more open witch in my opinion a female likes more if the male is honest. If they both respect one another and take care of each others responsibilities then there will be no problems
(Hopefully this helped)
Try Eating healthier, going for walks, and exercise often

An actual fingerprint is a mark left by the friction ridges of the palmar skin of a human (or primate). This is a very important research tool for forensic science.
A DNA fingerprint is a technic that helps identify individuals based on their DNA profiles. Although most of the human DNA sequences are common in most of the humans, there are several that can vary substantially from individual to individual - called variable number tandem repeats. As they vary so much from individual to individual, by comparison of the testing DNA with the DNA of any individual, it is easy to relate whether both sequences are correspondent to each other.
