If you've ever used Tumbler or, even better yet, Pinterest, the way Sex.com works will be familiar to you. This is a site for sharing porn GIFs, images and videos. Members pin pictures to the site that they found on different places around the web and other users can like, comment or repin them (add them to their own boards).
When you start browsing, you'll notice there's everything from gone wild girls of Reddit and other amateurs to pornstars and celebrities. There are lots of non-nude girls in sexy outfits. There's teasing, flashing and posing up to full-blown sex of every kind with no shortage of fetish and BDSM action, either. Besides straight content, you can also find a nice collection of gay, shemale, and lesbian material on Sex.com. New posts are pinned every day thanks to users, but there's no way to download videos.
Sex.com is, first and foremost, a great spot for porn GIFs but has a growing collection of various porn videos and photos as well. Content variety is excellent, but hot amateurs might be the best thing about this site.
