Dear Prudence,
I am a 47-year-old single man. I require that before I get physically involved with anyone she get full STD testing. Can you tell me why 99 percent of women refuse immediately when I broach this subject? It doesn't matter when I bring up this personal choice to them. Also, many people believe that wearing condoms gives 100 percent protection from STD transmission, which is not the case. People also don't seem to realize that oral sex can transmit a herpes type 2 infection. I have not had a relationship in many years, as I have not found any women who are willing to wait for STD tests before sleeping with me. Once I demand it, they walk away. Why?
