Well it seems then, there is nothing obvious you can do. I have not seen yout photo, but maybe a new haircut, or clothes...still in keeping with your style, but that may be more attarctive to the opposite sex. I am just speculating here though, as I couldn't see your pic.
You could also try onine dating maybe. I know you have said that this is unsafe, and you don't want to do, but should be ok with the right precautions and company. Alot of people have had success from this.
Apart from that, I have no other advice. I must say, you are begining to seem a lil less of an arogant idiot that you did before. So just hold on in there, be confident, be yourself...Im sure somone will come along eventually. Untill then, enjoy being with your friends, stick to college work...and your hand lol.
Hope to of been of some help
