My semen doesn't usually have a scent either...but sometimes it does so I assume thats the smell your talking about...maybe there was a sperm bank truck driving threw with a full load on its way to delivery when it was in a wreck and semen covered the road in a horrific scene that would make the most veteran of police vomit and cry...its a theory...do they deliver sperm door to door?...I know you can order animal semen...(for insemination purposes...I'm not that kinda weirdo...I'm the good kind).
