Is it possible that I'm not shedding the virus on my wife because my herpes rash site is on my butt and not my penis?

Hello everyone, I have a question about the Transmissibility of herpes. I've done all the reading I know about shedding when not showing symptoms etc I contracted herpes 15 years ago. I have been married for the past 13 and my wife does not have herpes. My herpes manifest on my butt cheek in the same spot every time about the size of a quarter. My wife of course is fully aware that I have herpes. In the beginning we were very careful but for the past 7 8 9 years we have not been. We have had unprotected sex consistently usually when I'm showing no symptoms. She has never contracted it. There were years where I did not take medication and there were times that I did because I just felt it was annoying to get the rash occasionally. Can somebody please explain this? Also was anybody aware of an anti viral lube? I can't find any would be nice of somebody made it. Thx
