I cannot remember the answer to my security questions, so now I cannot purchase from the iTunes store. Incidentally, I remember my password and can connect on my iPad.
iPod touch (4th generation), iOS 6.1.5
If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then the steps half-way down this page give you a reset link on your account : http://support.apple.com/kb/HT5312
If you don't have a rescue email address (you won't be able to add one until you can answer your questions) then you will need to contact iTunes Support / Apple in your country to get the questions reset.
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 link above to add a rescue email address for potential future use.
If you also can't remember your iTunes account's password then you can try getting it reset via http://iforgot.apple.com or by contacting support via the HT5699 link above
