Maybe you did not understood it well.From what I know , but correct me if I`m wrong , you can not read and write letters to a woman /girl.

When you are not a paying member.Also you cannot send a letter or receive a letter and read it.

This is only possible when you become a gold member.
However , as a standard member , you can send a wink to a woman.

But when she reacts to your wink , you must pay to see her reaction.

I hope that it is clear now ...
