To sexualize men for women, you have to understand women.

To men, attraction is largely visual. So to sexualize a woman for a male audience means making her look attractive, and dressed in a revealing outfit. Swapping the genders doesn’t work. A visually attractive man in a revealing outfit is far more likely to appeal to either gay men sexually, or men generally as a power fantasy. To appeal to women you need a fundimentially different strategy altogether.

Consider erotic literature. Its a genre that is disproportionately popular with women. Its basically anti-porn, no visuals all story. Male characters in these stories are almost always sexualized by women for women. The attraction mostly from their choices and actions than appearance. You need a completely different approach.

Go read some smut. Talk to straight women about who and what they find attractive. You have to learn a lot about women to appeal to them. What they are looking for, and how they are looking for it is entirely different from men.
