A very good way to make writing clearer is to replace the words that you don't care to know with other words that are completely inaccurate.

Question: how is it helpful for you to label them as a straight couple? Why would it matter to you? Why is adding the "straight" qualifier better than just leaving it as "they're a couple"?

The content matters though. If you are clearly and succinctly communicating something insecure and stupid, you don't get any bonus points.
