The mores relating to sexual activity are rapidly changing in the direction of liberalization in the US-- 10 years ago being gay wasn't popularly acceptable. On other fronts (polyamory and the galaxy of other sexual options) are rapidly becoming more acceptably and may be mainstream in another 5 or 10 years. Necrophilia, zoophilia and pedophilia aren't on the radar for acceptance yet-- possibly these will come after poly-acceptance (so maybe in the 2030s? hard to say) but I wouldn't be too surprised if they end up sticking around, considering that beyond their reputations those philias are actually harmful.
