In the Bible, Jacob fell in love with Laban's daughter Rachel, he promised to serve Laban for 7 years in exchange for his daughter.
Upon the completion of the seven year period, Laban took another daughter of his(Leah) to Jacob instead of Rachel and sharply Jacob had sex with her only to realize the next morning that he had sex with someone other than Rachel 😂😂😂 (Genesis 29, 1-29)
Question: Is possible to have sex with a lady without knowing her identity just like the Jacob and Leah scenario?
