(About men kissing and how people interpret such acts. There will be references to man-on-man sexual acts, so you should be prepared to exercise some judgment.)
A kiss is not just a kiss; it’s almost always something else as well. Sticking to the topic of men kissing men, we’ve got MSMs (“men who have sex with men” — but identify as straight) who sometimes won’t kiss men; and then we’ve got people who are offended and disgusted just at the sight of same-sex kisses, especially between men, and lash out in various ways, from having them banned from public view to verbally abusing the kissers to physically attacking them. These two reactions spring from two different views of same-sex kissing: for MSMs, who want “just sex”, kissing can be problematic because it isn’t sex, it’s affection and love, and emotional intimacy is not what they’re in the market for; while for enraged objectors, same-sex kissing is a sex act, and doing it in public is having sex in public, which is offensive, simply unacceptable.
Then there are people like me, for whom images like this —
— are deeply satisfying, because we see the kiss as embodying both loving affection and sexual connection, while not being in itself a sex act. Two responses, together: “Awww, so sweet!” and “Wow, that’s hot!”
