The way I see it, polyamory is about emotional/romantic connections by definition, but since the vast majority of people are sexual, multiple romantic connections almost by default means multiple sexual connections as well. I don't think "polyamorous + monosexual" is very common.
On the other hand, "monoamorous + polysexual" is pretty common, and some of these people misuse the polyamory label, which causes the misconception "poly is all about sex." There's another label for them - sexually open.
