This is indeed an adult related website, but for everyone commenting about malicious content, viruses, or malware infections, you should dig deeper before stating things of this nature. I scanned this website with 3 different services, and each one came up clean. This website has NO Malware, NO Viruses, and NO Malicious Code/Content.
You can check the results yourself.

hmmm... I wonder if this is a porn site.... WELL if it says "sex.com" wouldn't be obvious that it is a porn site? plus since of the "Obvious" name it probably has viruses on it! Unsuitable for ALL ages!
