You know back in my day VD was the buzz word and it was a very bad situation for civilians as well as military. Things have changed since then and the terminologies have changed, but the results of non-protected sex remain the same. There are at least 30 different diseases known to be sexually transmitted with most curable but some without cures. Scary situation and not worth the chance when there are ways of protecting yourself and others. Back during the American Revolution and a little after that sexually transmitted diseases were disapproved but disregarded. Then, up through WWII, the military used punitive measures to try and control the infection rate. That did not work and they were losing many of our military because of this attitude. The military figured out that these scare techniques did not work, they also found that penicillin and a less aggressive approach might work. Well as time went on, syphilis rates started to decline, so the military even stopped screening new recruits. We are now faced with some real bad STDs, such as HIV, chlamydia, herpes simplex virus and other real life changing diseases.
