Not sure, my homosexual friends don't seem to care. But I use homosexual as gay is often used as a derogatory term. Ie "that is SO gay". I never say that so want to be accurate when I speak.
I don't use the term partner for hetro or homo relationships. Oh and I know what it means I usually do not describe people using their sexual preference anyway, unless talking about the topic itself, not in an explainary way to describe someone.. IE I don't use it like, man/woman.. or brown eyes, blue hair.. skin color or height. I only use it when discussing sexual choices .

I use gay and my gay friends are not bothered by that.
Partner does sound businesslike. A guy I work with has a partner and it always makes think work.
I have a business partner in my side project and we stopped saying just "partner" because people thought it meant we were in a relationship instead of working on a project! Funny.
