We see no hint of tongue, no groping fingers fumbling to unclasp a belt, nor even a nearby massage table upon which one might suddenly flip over, cast a modesty towel aside, and inappropriately request their meeting conclude with a happy ending. There is none of that here, just an innocuous image of two, avowedly heterosexual males.
So if they should offer a platonic, same-sex pal a fond, lip-to-lip greeting before takeoff, who are we to judge. That is if they should, that would be ok. lol!
