I'm pretty sure that you didnt get it from your docotors office. They know what there doing. Most likely you or your hubby got it from somewhere else. There are two types of this virus, 1 and 2. 1 is generally on your mouth and lips where as 2 is on or around the genital area but either can be on either part of the body. More info on Herpes 1 and 2
Both are very easy to catch and you could get them from sharring drinks or giving a quick kiss. Also one of you could have been carrying this virus for many years without any symptoms. Some info on why Std's don't show up right away. both on the same site.
