an option to invite people from your friends list to watch a xhamster video at the same time, with a chat bar to the side of the screen so you can talk as you enjoy watching the video together. this is quite a popular and enjoyable niche, people who masturbate to porn online together, there are several platforms outside xhamster to do this on, however, no porn tube site, to my knowledge, currently has it implemented yet. An option to "Invite friends to watch this video" would seriously put your platform ahead of the crowd of porn tube sites.
