What is the attitude toward homosexuality in Buddhism?

I am specifically interested in the attitude of Theravadan Buddhism toward homosexuality (if it has one at all.) I don't recall ever seeing any references to homosexuality in the suttas...I do recall seeing some non-normative sexual activity discussed in the Vinaya (or its commentary) but am not as familiar with the Vinaya. If anyone can speak to the Vinaya on this topic that would be helpful. It seems right to assume that homosexual activity would not be treated any differently than heterosexual activity, but the fact that I do not recall seeing it ever discussed, along with general cultural attitudes expressed (e.g., statements by the Buddha (as I recall) that there is nothing more attractive to a man than a woman and vice versa) makes me wonder if I am missing something. Also, if anyone has any contextual information about the culture in India at that time that would point to why there would be no discussion of homosexuality--e.g., it was absent--that would be helpful.
