I've made the mistake of curing my lycanthropy twice. I had previously been under the impression that I could go back at will, but after talking to Aela a few times, and a bit of research online, I was a little heartbroken to find that it was currently impossible.
This is especially poignant due to that my second infection was 17 levels ago, and my subsequent curing was 13 levels ago (I had decided to try out being a Vampire Lord). Going back would negate many, many hours of play for me, which is something I would very much like to avoid. Similarly, I can easily see myself avoiding ever taking advantage of becoming a werewolf again, simply because I would know that it would be my last time, and if ever I wanted to go back to being a vampire or being neither I would end up with the same problem I have now.
I understand that being a werewolf is supposed to be something 'rare', and that going back and forth with abandon offends some people's perspective when it comes to role playing a character. I do not want to have that discussion; I understand that position already.
What I do want to know: Is there any worth in hoping for an upcoming patch or fix that might allow multiple werewolf infections, similar to how one can become a Vampire Lord (and cure one's self) multiple times? This would greatly enhance my gameplay experience.
I'm on 360, so Mods and the like seem to be out of the question, unfortunately.
