As funny as it sounds,this is actually a thing. I know of same sex couples where they are both gay and masculine but one is "super-friendly" with women if you know what I mean and the other gets completely jealous which makes no sense whatsoever because he's not even attracted to her,it even destroyed the relationship of a friend of mine,they were already engaged and were ready to settle down but turns out his "fiance" didn't like him being "super friendly" with women and my friend is super hot and really masculine so women would hit on him sometimes not knowing he's gay and he made friends with many of them,he makes friends with anyone regardless of gender or sexuality. The day they broke up is quite similar to that pic of Zane with the girl but with more nudity,my friend went skinny dipping with their female friends and he was the only guy with them,things went south as the women were jumping on him,you know just beach play where you splash and play in the water,just right there,his fiance dropped the ring and left,he said he found it insulting. I think it stems from insecurity because months later,we found out the guy had dated three men in the past who left him for women so it doesn't matter whether the guy he's dating is bi or gay,he will always see whatever he wants to see when he sees a man he's dating with women
