I know what you mean. I'm only 19 and I'm not looking forward to a life of being gay too much at all mainly because the chances of meeting a nice guy and staying with him are admittedly slim in a world where women outnumber men, too many men are fixated on little more than sex, and men tend to focus more on the physicality of relationships than the emotional. Now there are exceptions, but it hardly matters because 8/10 gay men you run into will most likely just be cruising for anonymous sex or simply looking for someone who perfectly meets their standard of physical attractiveness. As much as I hate it, I must confess that that is natural with most men. 
 
I may meet some nice guys in the better part of my youth, but I suspect that once I hit a certain age relationships will be all about sex and little more, which is not a lifestyle I'm interested in living. Ever. 
At least if I were straight I could possibly look forward to a future that was more romantically and emotionally stable because I believe I am much more likely to find a woman who is interested in true romance and monogamous happiness than a man. However, as a gay man I may be fortunate enough to meet someone special, but the chances are not in my favor and I have no use for a life loneliness. Anyone can feel free to argue with me here, but I suspect most who would have not had a partner for longer than 5 years at a time, and if they have then they are definitely one of the beautiful exceptions that almost makes me hopeful. Almost.
 
Anyway, I have started to realize just how little I look forward to a life of being gay. I don't want a life of constantly searching for someone who could kill a bit of the deep loneliness I feel and only coming up with shortterm relationships only built on sex and physical attraction. For me it isn't worth it, though for others I realize it is. But I'm sure I couldn't handle being 54 and alone or trying desperately to cruise for sex while hoping I don't have some form of HIV lying dormant in my body. Loneliness is a special kind of misery and after a while it snuffs out your light. 
That's probably why at this point I have so little interest in even seeing my 20th birthday. But that is another story.
 
Call me a cynic...
