Would you be able to do a scene with a member of your family if its just acting? - read whole question pls?

come on now i keep on hearing people saying that if its acting then its not the same as in real life , so would you be able to French kiss one of your immediate family(mom or dad or gran) if you are acting and in character , watch i know what you gona say that’s sick. The reason i ask this in the section is what I am saying is no straight man could not kiss another gay unless he was gay or bi ual, because as sick as it seems for you to kiss a family member , that’s the same way all straight men feel about kissing another guy – they are repulsed by it –as they should be since they are straight , why do gays insist that guys like Heath ledger/jake in broke mountain are not gay , when they clearly are , as any straight man would find kissing another man over and over again just as repulsive as kissing another family member do you agree , there is line you just cant cross in acting (like kissing family members) even if its acting and if a straight man kisses another man for what ever reason surely crossing that boundary he MUST be gay or bi , what do you think ?
