Semen is life. It's only natural that some men would become sexually activated by the sight of cum on a woman once turned on. There's nothing shameful about men being men and eating cum. Don't give away your man power to sex shamers afraid of natural male sexuality.
A lot of men would prefer calling themselves a cuckold rather than bi, when they demonstrably behave bisexually. I argue that most, in fact almost all cucks are bisexuals. There’s nothing shameful about living of integrity in your authentic sexuality.
