Is my MBP infected? Questionable Website

Hello. Earlier today (yesterday eve around 5 PM) while googling for a series of photos of a child having a lumbar puncture for a Photoshop project, I chanced to come across this website (link)

<link removed>

this is a link to that site in question, and looking back at this hour, I'm wondering if I had accidentally visited a porn site (absolutely NOT what I intended) and am worried that now my MBP might be infected with malware from just simply visiting that site and if I'm going to lose all my files/folders again like I did this past April 2010, and if the external hard drive I now havd connected to my mac is also infected (I hope not)?

There is no drive by malware that infects OS X. If you installed nothing, didn't put in your password, then you are infected with nothing.

PS. Also no viruses. As in "at all."

I didn't review the photo(s) you linked to as I'm sure it's nothing I need/want to see. Keep in mind that this is a family-friendly forum and so we really don't want to link to any pictures that don't have a 'G' rating.
