I took a "Love Poetry: Sappho to Shakespeare" class in college, and yeah, the Greeks and Romans were a bunch of pervs, gods bless them. If you were entertained by this, there's a hell of a lot more where that came from.
The book in that link is neat, too, because it's an intentional effort to strip all the prudish Victorian crap out of the translations and present it with some like the, uh, full repetitive force of the originals. And yes, that is a reference to sticking cocks into people's bottoms, because if you can't handle that, you REALLY shouldn't read this anthology. :)
