I've encountered a list called "Normal Couple (Man x Woman)" and... dearie who made the list, whoever you are, M/M, F/F, etc are also "normal" couples. Watch your wording choice. This is the 21st century. It's time to stop referring to all things straight as "normal" and realize that consenting adult couples are normal couples, no matter their sex and gender.
