I got asked this question as part of some shitty “party” board game a year ago and I truthfully said “Yes” to the question of “Have you ever thought of someone’s in the room’s spouse naked?” and apparently my friend and his wife got really offended about it. They’ve since recovered but you would think I had literally described having graphic fantasies of a threesome with both their mothers. They claimed that “No mature adult thinks of things like that”
If I randomly think of my friends wife naked and I’m not acting on this impulse and am keeping it to myself except when being directly prodded to say it, how is it not okay to do?
