I saw him pee, and I fall in love with him!

Few months back, I saw a co-worker standing in front of the urinal in the men's room, doing what he had to do (nature's call), and since that moment I fall in love with him. I started visualizing alot of love scenes between us, day and night, and i become obsessed by him, of course he doesn't know anything. I really love him, and I want to spend the rest of my life with him. Some people would think that sex is driving me, but it's not, though it's a major part, but the main part is that i want him to be a part of my life. I masturbate alot, thinking about him, even thinking about him makes me hard! what shall i do? Help will be appreciated, fellow posters>
