To add on to the advice others have already given: Are guys just simply not asking you out, or do they reject any advances you make because of your height? If it's the first, then there's a chance that people aren't necessarily put off by your height, but might think they have to be so many inches taller than 6'2" to meet your standards (I know I probably would, even if I had met you and thought you were pretty great). If you think that might be the case, then go ahead and try asking that guy to meet for a casual cup of coffee or whatever, just so you can show that you've got some interest and get the ball rolling without putting to much pressure on yourself.

But as a dude who just finished his undergrad years without ever going on any dates, I do understand your frustration. If God's going to make you wait for this period of your life, don't forget that no one individual will fulfill all your needs. God's got you covered, even when it doesn't feel like it, and that's something I've had to remind myself time and again.

Still, we're rooting for you in your quest for romance! :)
