Trust me, gay men are no exception. Str8 men are also trying to hook up with the hottest female available. Just like everyone else, they discriminate, too.
As we age, yeah, doors start closing and there are less opportunities. You are right.
However, if you look back into the big picture, you'll see that for the most part, human existence is actually a constant negotiation with various forms of discrimination.
A 16 year old, who is allowed to work and earn his upkeep, usually feels terribly discriminated, when the doors of that particular club stay closed for him for the next 2 years. Let's even not touch the subject, 'you can go to war, kill and get killed, but you can't legally buy a can of beer'.
A cool looking young friend of mine happens to be African. He is mostly rejected despite his youth and good looks, as many (not all) people around here would rather stick with their own race.
If you peruse a number of profiles on various dating sites, you'll find the ubiquitous, 'pls., no fats, no femmes, no asians, no older guys, no this, no that'.
Sexual selection necessarily involves legitimate discrimination.
You choose your sexual partners not by the instructions and requirements of the anti-discriminatory legislation and policies, but purely based upon your personal preference and the availability of desirable partners at that time.
This is a very universal principle which spreads throughout the animal kingdom and is certainly very universal in many human cultures.
It is a grave error of judgement to confuse discriminatory practices in housing, education and employment opportunities with those pertaining to sexual selection. They belong to the two very different worlds and should never be interchanged.

Like with every other challenge in life, your first strategy is of a political nature. You want to determine, what is it that you can do (vs. what is it that you cannot do), in order to increase your value on the dating, sex, meat or any other 'market', if you will?
You cannot really stop ageing and you cannot really change your race. You cannot grow a 13-incher just because that hot and super desirable guy next door happens to be an incurable size queen. Indeed, there are quite a few things that are well-entrenched within the realm of impossibility.
Yet, you want to focus on what is both viable and doable.
You can reduce your body fat and nicely tone your body by regular exercise and good diet.
You can make sure that you always dress right and look as attractive as you possibly can. (Birkenstocks with white athletic sox are always a bad idea.)
You can take good care of yourself, have a good hair cut and use the best skin care there is. Guy who do so are sending a very powerful signal: If I can take good care of myself, there is a chance that I am good at whatever and maybe, I can help you, too. This might be a sublime message after all, but the one to which many people are extremely susceptible to.
You can choose to adopt a healthy lifestyle. Reduce your drinks and ditch the cigs. Get sufficient sleep and dump all the junk food and never look back.
You can choose to project your strength and your power forward into the world. Genuine self-confidence tops many people's priority lists, when it comes to searching for a serious partner. Not every hot athletic jock out there is looking for some kind of a 'daddy' but quite a few are. At times, self-confidence, sense of stability and achievement, financial security all coupled with a sense of discretion work those small, daily miracles.
You can choose to live in a major metro area. You need all the opportunity there is.
