sxxxy_feed - Has been promo-ed here before, but nyxx from metafilter has his (her?) own sex news blog, syndicated here.
Now, of course, the reasons for posting things here are reduced, since the points system has died... and yet I swear the # of posts are up
FYI, both feeds are text-only, so SFW, iff you don't have someone over your shoulder at all times. However both their linked articles usually have at least one pic, and sxxxy's always has an NSFW banner ad.
Of course, if you're reading LJ at work, and looking at friends filters that have sex in them, there may be other problems.
