You can get in contact with the closest LGBT group or circle, or you can attend places and events that you know are usually popular among LGBT people, like certain pubs or clubs. Or you can even try dating apps if you are into that.
Like the Lottery, your number may come up and then again, it may not. Be secure in yourself, enjoy life, your activities, sports you like. Use friends and acquaintances. Do not settle for second best because you will live to regret it. Look to your local gay center for social activities outside the bar scene; try a gay campground or gay bowling league, a chorus or your local gay friendly church.... to coin an old phrase: we are everywhere!
You look. Or you wait. Maybe go on tumblr, search up something you're attracted to . Then start off with who you find attractive, go on their blog look at their interests. Do you have something in common? Start up a conversation, and go from there.
Listen to both your heart and your head! Do you have something in common that you can connect with? Does anything negative stick out about them? Make sure you listen to yourself, only you know the person for you!
What qualities are you looking for in a partner? I would start by making a list of the things you would like. Then put this list in the order of importance to you. Because realistically, you may never find someone that will meet all the requirements that you may come up with. Then decide how you are going to find this person, a dating app? Community hikes? Museums? Church? Music Festivals? Volunteer work? The world is a big place so be on the lookout for the top qualities on your list.
There are so many different ways to find someone suitable for you. I personally met my girlfriend online, but I've previously dated people from school and other activities. You just have to put yourself out there a bit. It'll happen when you least expect it.
Many times love finds us, not the other way around. You find what you're looking for when you stop searching for it. Love also can't be forced. Step outside your comfort zone but don't make finding a partner your priority. Often times you'll find that what you're seeking will come to you with patience.
Join social groups that have a focus you feel passionately about, anything from hiking to animal rescue to religion. Successful couples have interests and beliefs that align.
Don't rush into relationships if you want to build something that lasts. It's easy to become infatuated and put blinders on when you first "fall" for someone.
