She doesn't have to be a ho, just stupid/careless! My BFF's H (allegedly) cheated just once, with an OW who (claims to have)cheated on H only once on her H, and my friend got an STD from him/them.
Better safe than sorry!
it IS better to be safe than sorry but
someone in that story of your bff's, isn't telling the truth.
Or they do some wacky intense and unusual sexual things...sorry but I don't believe it.
I had a lawsuit involving a defendant with HIV who had sex with OWs. They sued and he was also charged with "attempted murder" which I objected to b/c there was "no intent" on his end. Without going into the legalities and technical jargon of the case
I ended up learning a lot of stuff about STDs that I did not necessarily ever want to know. But among them were the "least likely methods of transmission" and the "most likely."
Based on that info, either someone in your friends' situation is lying (most likely)
or they have the worst statistical luck possible on all ends b/c it would mean that the man the "careless OW" was with, transmitted a disease to her with ONE event, and that she then transmitted it to the bff's h with a One night stand... and that he then gave it to her...
In sum,
It is MUCH more difficult for a Woman to transmit an STD to a man, than it is for a man to transmit it to a woman.
but do what makes YOU feel safe, Life.
If he made the appt then the MD will know what to test for and he can tell the doctor what types of sex they had, if drugs were used, etc.
I would not want a lot of details if it were me. Just a clean bill of health.
