If my husband tests negative for stds, how could i get 1?

Who knows?: Being negative for stds on testing still does not guarantee for 100% saying no stds because all the tests have their false positive or negative result. Furthermore, many men and women are asymptomatic carriers notably for hpv, herpes, chlamydia, etc. In real life, we have to keep up good health to win the war against bacteria, yeasts, virus as much as we can through practicing healthy lifestyle.
