Why does after making love always smell an unpleasant smell?

When making love, both male and female organs have secretions, which will release some smells. Under normal circumstances, it is a faint protein smell (similar to egg white smell) mixed with some urine smell left in the urethra, which is not strong and annoying, and this smell will not change much.

However, if the sex organs or urinary system are diseased, the female vulva is unclean, and the male foreskin is unclean, it will produce a strong and unpleasant strange smell, which is not fixed and needs to be carefully found out and solved.

Another situation is that there is groin body odor, which will also give off an unpleasant smell.

Therefore, the vulva must be cleaned before and after sex.
