Fortunately, I don’t have to worry about this too much. There is no chance of us getting pregnant, and even if one of us were to cheat, the likelihood of STD transmission
is very low between two women. And if I were to cheat, I’m the only one who might be with a man, and I’m not stupid enough to have unprotected sex.
I agree with casheroo, get tested, just in case. You never know.
