This cam site claims to have tens of thousands of users online from around the planet at any given time.
If you are looking for very popular and 100% free random chat sites like Omegle or Bazoocam, you won’t be disappointed by Chatrandom.
Try the ‘Girls Watching Guys on Cam’ chat room for best chances of success, though some of the other chat rooms will work equally well.
Granted, there might not be as many girls on there as there are on some of the other sites mentioned here (apparently, Adult Friend Finder has a 16 to one male to female ratio), but given the nature of the site, you can get from chatting to sex much faster than with any of the other chatrooms below.
It will also work better for you if you actually have an interest in languages.
However, the main advantage of the site is that it connects you directly to other users, and that you have the option to select them by sex.
However, it has recently introduced ‘Tinychat Next’, a random cam-to-cam service similar to Chatroulette, and it has made it easier to find cam sex on the site. Because it is relatively new, it seems to be free of all the spam omegle suffers from. However -like omegle and chatroulette- the site bans you for nudity, and its business model is to ask you to pay to get unbanned.
