Suppose two partners male and female engage in oral sex and the male ejaculates, he uses tissue to clean his penis but some of the semen gets on his hand and he uses tissue to wipe his hands dry then proceeds to finger his partner (female). They get scared about the possibility of the female getting pregnant and they purchase postinor 2 which contains levonorgestrel and she takes the two tablets at once. My first question is should they have been worried about the girl getting pregnant in the first instance and would the drug work?
