I believe what you lack is confidence. You probably seem shy and timmid around women so you go unnoticed? Find something that you love to do. Softball, bowling, church. Find a passion and come out of your shell. You will meet someone. As far as dropping libido i think its a bad idea but they do use the depo shot on sex offenders to chemically castrate them. I dont think thats the wise choice though. Id go for stepping out of your comfort zone. Get a new outfit haircut and smile and be socialable. People fall in love with souls not looks. Looks get you the wrong attention and can actually complicate relationships. You think someones in love but its just lust. Get to know a woman on a deeper level than shaking her hand. Find common interests and friendship then see where it goes.
