Almost sounds like Children Shouldn't Play With Dead Things, but I don't recall that movie having any nude scenes with bacon.
I remember watching a zombie movie when I was a kid, I think it was called Island Of The Dead. That had sex & nudity in it, but most of the characters weren't college age, they were in their 30's & 40's.
A more recent one where the characters go to an island by boat is Survival Of The Dead, but again I don't recall any sex or nudity in that movie.
Don't know if that helps or not.
