If you have one spouse, if that one is trustworthy, you have no worries. But if you marry yet another person, that person must ALSO be trustworthy, or you are at risk of STDs. And if you marry yet another person, that person must ALSO be trustworthy, or you are at risk of STDs.
Basically, all it takes is one person to bring STDs into the relationship. So if there are two people in it, there only need to be two trustworthy people. If there are 10 people in it, ALL 10 must be trustworthy or ALL of you are at risk of STDs.
The risk of you getting an std, if one out of ten cheats, is the same as if one out of one cheats. The other nine in the equation do not add to the risk pool if they are faithful. I see your point if 2 or more are cheating because now you would have two cheating partners as opposed to one.
That is irrelevant to my posts. Of course if you have a cheating spouse, you are at risk of getting an STD. That is not the issue. The issue is, the more spouses you have, the more likely it is that one (or more) of them will cheat. You are not guaranteed to have a cheating spouse, so you may not have any cheating spouses at all. But the more spouses you have, the more likely that at least one of your spouses will cheat on you. Consequently, the more spouses you have, the more likely you will get an STD.
