Well, my H would probably give his left...er..hand if I said yes to a F/F/M ‘experiment’. Of course, he always says he’s joking but I bet a lot of men would love to have at least a one time shot at it. My sister once jokingly kissed a female friend while out at night and every guy in the place wanted to join their table. Most adult movies include at least one chick on chick scene, because male viewers love it. And some females, no doubt.
Of course, I told H I would be more than willingly to indulge him in a threesome. I told him to ask a few of the guys he works with if they were interested. His enthusiasm waned a bit after that ;)
I'm no prude and no fool. Sex sells. And “taboo” sex that be made to look acceptable sells the best.
But look at where we are compared to 40 or 50 years ago.
I don't think the sexual revolution has done anything to help society but has caused a lot of damage. I bartended in a very “hip” bar that was probably about 50-50 straight/gay. Believe me. I've seen everything and nothing shocks me anymore.
But when I see the effect this is having on children who are still in high school, it really does piss me off that adults are willing to take the morality of this country down the drain for their own taboo thrill.
