Please imagine a girlfriend-boyfriend relationship which a very close or even romantic (meaning sexual or non-sexual) relationship exists between them. For me, there is a very common way to describe such a relationship:
"They are going out." or "they go out together."
My question: We use the above-mentioned sentences to explain a relationship between opposite sexes, but what about the same sexes? E.g. two boys or two girls? (Sexually or not sexually.)
I am looking for an equivalent for "going out" (which for me, can be used only when two opposite sexes are involved in a relationship) for same sexes, meaning two men or two women.
Added: what makes me believe that same-sex couples need a different word is the fact that usually/normally in same-sex relationships there is no any romantic sense while normally/usually the opposite-sex couples have a romantic feeling from the beginning. This is the matter.
