Well, when looking at sexual references in Greek mythology stories, it's important to consider the context. Some stories, like that of Eros and Psyche, had elements of sexual tension. Eros was sent to make Psyche fall in love with a hideous creature, but instead he fell in love with her. The sexual undertones in this story added to the overall drama and the exploration of love, beauty, and the relationship between the mortal and the divine.
In Greek mythology, sexual elements are indeed present. Take Aphrodite, the goddess of love and beauty. Her very existence was centered around love and sexual attraction. Her relationships, like with Ares, were full of passion. But we should also note that these stories are a product of their time and culture. They were a way for the ancient Greeks to understand the world around them, including the powerful and often confusing forces of love and sex.
