These tools can be used within a tantric sex context.
Most of the times, of course, the tantric dimension is not present in what you will find online.
It’s up to you to introduce it if you want to.
You can for instance record some tantric sex videos with your partner and discover a new dimension of beauty and excitement through that.
You can connect with someone online and use your webcam as a medium to experience tantric sex with them.
All potentials are there.
A webcam, video or chat room is simply a tool. You can use this tool in whatever way you want.
