As a gay man who has been frustrated at every turn on a journey to explore options for starting a family, I hear you OP. 
Truth is, straight people don't know what it's like to be gay. It's not their fault. It's enviable in a way, frustrating in others.
Because the majority of straight people have never had to wrestle with their sexuality, or question it. They've never had to define themselves against what family, friends, society expect them to be. (And keep defining, as coming out is a lifelong process.)
They've never held a boat-load of internalised shame about attraction and love, something that is fundamental to a person's very being.
They've never had to consider how even small actions like holding someone's hand, applying for a tenancy agreement, meeting new people or going on holiday could leave them open to, at best, confusion and thoughtlessness, and at worst, outright abuse.
They've never, as a group, been elided with paedophiles and animal abusers by national newspapers.
In the 80s and 90s, they never had to bury dozens of their friends due to a mystery illness that the government wasn't especially bothered about treating, because it seemed to be killing off the problem.
Ultimately, things are better - for now - but it's still a straight world. We have to overcome a whole load of shit just to live in it.
