A friend met with a Scottish escort in Scotland. She has her own website. He kissed her and she spat in his mouth and they engaged in French kissing. He also licked her vagina and she squirted in his mouth which he swallowed. He then licked her anus and she shit in his mouth too which he swallowed. He said there were a few red papules in her groin area which she said were razor bumps from shaving. He is very worried about his risk of STI. Which STIs is he at risk of and what are these risks. Are the risks low enough that testing is not required? Are the risks low enough that he can continue to have sex with his wife? If he decides to get tested, what stis should he test for and when should these tests be done. What in the real world can the risks involved be related to for comparison?
