How do I activate my sdb5 partition and have it stay active continually.

Oops, close that without saving.

A 'mount point' is nothing more nor less than a directory.  If there is 
nothing in it, it can be removed with an 'rmdir', see the manpage.

If there is something in that directory, probably because something was stored 
there when no media was mounted, then if its precious, mv (see the manpage) 
it to someplace safe.

Now, please understand that if I had a /media/westernsteer directory, I can 
mount any partition visible to the system on that mount point with the mount 
command.

Demo (all as root or sudo'd, and the # sign is the shell prompt, no pound sign 
its the response to the command:

# mkdir /media/westernsteer
# df
(and get:)

The above to verify where my /boot is (this box is an odd bird), then

# mount -t ext3 /dev/sdb1 /media/westernsteer
# ls /media/westernsteer

It is in fact, my /boot partition, mounted someplace else.  Now, clean up the 
mess I just made:

# umount /media/westernsteer
# rmdir /media/westernsteer
# ls /media/westernsteer
ls: cannot access /media/westernsteer: No such file or directory

Does this help your understanding of how this works?
