Problem:
how allow subscribers to read their own posts only

Solution (include the steps to follow here):
You can use a wpv-conditional as example.
Let's say you use a Content template for all your Posts, in this content template you could check if the current logged in user is the author of the post.
A shortCode like this could work:

[wpv-conditional if="( '[wpv-current-user info="id"]' eq '[wpv-post-author format="meta" meta="ID"]' )"]
//Your content here
[/wpv-conditional]
