I don't think there's any harm in it if both parties enjoy it.
Many women are highly verbal; words can switch on their fantasies in ways that the unconscious can't separate from the real - which can be a powerful experience for people with vivid sensory imaginations.
But if it doesn't turn you on, there's nothing wrong with that.
I do think anything that leaves a permanent record is potentially dangerous in the sense that it could later be misused.
For this reason, I believe sending photos, video clips or live on camera is unwise with anyone you don't already know very well. I'd want to know them in person for several months at least. And then, if we were separated for a while, sexting would become a great way to bridge the gap.
If the relationship breaks up, a mutual ceremony of wiping all sexts and images while in each other's presence - and swapping phones and computers to allow each other to check - is a good idea.
Sex and love online is fraught with many difficulties.
There is probably a pressure among younger people to conform with what might now seem normal.
It can work to meet and initially explore getting to know someone,
but ultimately it's meeting and getting to know them in person that makes the crucial difference.
If that is not geographically possible from the outset, might be best to give it a miss.
