It may be true that heterosexual men want sex. But so do heterosexual women and homosexual men and women as well, as well as those who are somewhere in the vast spectrum between these identities. The question to consider then is why does male heterosexual lust get special consideration?
For example, consider the framing of calling the ability to reject male advances "power". Anyone can reject sexual advances from others for any reason, but it's rarely framed as a special position of "power" other than when applied to heterosexual male advances.
