These threads are strange to me in that the overwhelming response always tends to be "haha females, amirite?", as if people's only exposure to women in relationships has been through low effort sitcoms or when their buddies are venting at the bar. Women don't look for ways to be offended by their partners or misconstrue words/intentions to create petty drama. They're not evil beings who feed off negativity or their partner's frustration either. They're people just like you and me and their personalities are just as diverse as ours.
Citing anecdotes of women being picky or dramatic shows nothing but your own bias.
As for the advantages of being gay, I've always felt that we are given more opportunities to think introspectively since our identities challenge the default. We are conditioned to believe certain things or to behave in certain ways that are often just reflective of cultural ideals, and I believe it's significantly easier to recognise conditioned thoughts when they are a direct contradiction of our identities. I say that we're only given more opportunities for introspection because, as noted above by bankside and lucky, many tend to perpetuate restrictive gender roles or struggle to recognise their conditioned thoughts despite them being largely inconsistent with homosexuality. Conversely, I think it's much easier for straight people to avoid questioning much of their conditioning as it tends to be consistent with their sexuality.
I also enjoy the sexual versatility of being able to top and bottom. I get to feel a partner inside of me, and he gets to feel me inside of him. Prostate stimulation is a beautiful thing, and I'm not sure it can be experienced on the same level with a straight couple and some toys. Then again, that's probably more of a personal preference thing than a universal advantage, as many gay men do not enjoy anal, and many are not versatile. I still believe it's worth mentioning though.
