Dating is a complex, nuanced process that involves understanding the nuances of physical intimacy. When it comes to physical intimacy in relationships, there are many factors that come into play. From connection and trust to communication and respect, all of these elements can contribute to healthy physical intimacy between two people. One element often discussed is why men are attracted to butts, which some may find surprising. A study conducted by Oxford University suggests that the shape of a female's bottom could be an evolutionary signal for males because it indicates fertility and maturity.
