Free online sexchatting without login
In the early days of the internet people mostly used it for simple forms of communication like sending emails etc.Options to communicate were very limited at that time so the possibilities for erotic chatting were subjected to those same limitations.
Many of the chat portals on the web require users to signup and give your email address in order to use the services.
Everyone was talking in the same window and if you wanted to have a private conversation you could invite the person of your interest to chat in a private window. Basically that still happens on a massive scale today.
At some point in time, phone sex was something that started making its way.
There are many free chat destinations online that are 100% free, but many of those require you to register and give up your email address in order to use them.
Most of use do not want any more spam, and so we are reluctant to give up our email address, especially to adult or porn companies.
