Divergent sexualities

[FrustratedFool]

Yes.  
An OS may be sexually attracted to an object without falling in love.  Or an asexual OS may have the reverse.  Many have both experiences.  Same with all other sexualities, I expect.

Considering it's really love it's just used as a relationship requires two thinking entities

The sensation of love, as a state of neuro-chemistry, requires only one being. Theoretically, one could have the sensation of live induced by a drug. After all, if one feels love in a dream (and I certainly have), then that is exactly the same thing.

Of course, if you are using the word love to describe not a particular emotion but a particular type of relationship and a conglomeration of other elements external to the brain, then it becomes a more complex debate. But I think it best to use the term live purely for the inner subjective emotional experience and the term relationship for that more expansive idea of personal ineraction (in that case I've already talked about illusory or psuedo- relationships).
