The title should translate to something like "He's Hard to Deny"
or "It's Hard to Deny" (that you're gay/ that he's gay).

The horror of turning to stone parallels the embarrassment of getting an erection in public.
Literally and figuratively getting hard for each other. Although I can't say for sure if it's a matter of reputation or if they're denying their sexuality as well.
