Just because you are poly doesn't mean you Willy nilly sleep around.
I dated quite a bit outside my marriage. Murf has been my only sex partner.
As for the herpes issue. There is no way in hell I would put either of my husbands health at risk by sleeping with someone with herpes. None of us have the infections.
40 yo straight female
Married in the eyes of the government to Butch since 2001...
Murf my monogamous second husband has been with me since May of 2012.
In a V relationship with an average 60/40 split of time. Only due to Murf's and Butch's crappy work schedules.
