This might sound so far fetched, but I'm pretty sure there's a psychological thing within Gays, who've maybe not had great acceptance their whole life, and have constantly tip-toed around relationships and had a lot of cover-ups etc. during their early life as a gay and it makes them kind of loveless.

Not completely, but in the sense that growing up, you're still outcasted and male to male or female to female sex is still seen as weird, so depending on how long you've avoided it, and depending on how shallow you are, when some gay people finally break into the dating scene, relationships can be too sex-driven and aesthetically powered, they're never gonna work out.
