You would have to have sex with the railings to have a slight chance to get something...even at that I still would say there is NO risk for STDs from having sex with dirty railings.
Nothing (No STD known to man) could have infected you from what you are worrying about (germs on dirty railings).
yeah but than even those fluids would of had to mix with my fluids which it didnt.. cuz she just touched the base of my penis yeahh thanks i shouldnt realy worry.
It is possible - but EXTREMELY unlikely. Like probably less than .01%. Unless someone else had put their bodily fluids on the rails earlier in the night and then she transferred their fluids to your penis, it is almost impossible. I wouldn't worry about it. =)
