Hmm, it's interesting that you continuously reiterate that one must be human as well as consenting; so you're saying if an animal were, hypothetically, consenting it would still be wrong to have sex with it? And is this because of the associated taboo that society places on bestiality, or your own personal bias?

I understand it's wrong to have sex with an animal under normal circumstances, because they cannot truly give consent, but I find it funny that love must be specifically human. It provides restrictions not really necessary, doesn't it? Same thing with age; a limitation I don't see as necessary as long as there's consent.

If it's a conscious choice between two people to be together and "love" each other, and if they understand the implications, then shouldn't it be okay? Therefore, the only restriction to love should be consent, right?

Just my 10 cents.
