Download navetsea skins sims 3

Not sure where to put this, but the misc chatterbox seems like an okay place.
I've been over to the TSR website downloading a few new hairstyles and a few clothes and I noticed many of the sims in the pictures (the men at least) have nipples. So I Googled this and found out there is somewhere you can download these 'skins" so your sims are anatomically correct. But I didn't have any luck finding just where to go and the one website I did find seemed like there was no active members and I couldn't find how to download what I was wanting or the one I did manage to download I couldn't make it work. (the instructions were missing on the site too, so I gave up cuz this didn't seem too computer safe)   Does anyone know the where and how I can find this? I'd at least like the top half of my sims to look normal. I get why EA wouldn't give them all their parts, but why wouldn't our sims at least have nipples? The women with are blurred anyway (unless you have decensor) and anyone can go to the pool or turn on the TV and see every guy has them so it's not like it's something dirty. 
I don't equate nudity with sex anyway and IMO it's hardly even in the same category other than one is generally naked when woohooing.
