thats really it. the vagina has many exposed areas that are considered mucus membranes. the mucus membranes are what attracts the virus. with such a small opening in the penis its possible just less open area to expose unless there is a cut or opening of anykind on the outside from other events.
That makes sense. Thanks!
I believe it has to do with the greater preponderance of woman's delicate labial skin; a bit more welcoming (unfortunately) to the virus being able to be transmitted.
