You can connect to all kinds of phone sex operators (PSOs) when by just dialing a single number. That means you get real women, not professionals handling the calls.
While some guys prefer to give up control and be guided by more experienced PSOs, other like to chat with beginner operators which are often more innocent (and even a bit nervous) girls who can be guided by the caller.
If you are smart about it (and you message enough girls), you can enjoy phone sex for free by calling into these phone dating chatlines.
Fuck Swipe is a popular — mobile only — hookup platform.
If you are seeking the girl next door experience, at least give Fun Sex Phone a try.
