Sorry to hear that. But don't take it so serious! 52 days, that's a lot. I'm really grateful that you started this thread, because for me it was a good time and a good undertaking. Maybe I should not have made such a silly competition out of it. I just thought it might spur the motivation between all these demotivating cautionary voices, and indeed it spurred mine. But I didn't want to turn it into something grim.
Actually I just came here because I wanted to relate a funny story to lighten things up a little bit of how I got a crush on a bhikkhuni on a meditation retreat this weekend. Man, I have not felt such butterflies in my stomach since I was 16. But okay, I'll spare the details. It just ruins the romance. At any rate, my new suggestion to tackle the problem is to fall in love with a bhikkhuni if you find the opportunity while trying to learn meditation from her. And then you have to seperate love from lust and admiration from infatuation and sort these things out and your interest for sex will just disappear in the process. Or maybe that's what Mara told me.
Okay, almost enough silly advice. But one more thing: Don't feel humiliated. I really appreciate your initiative and your honesty. Don't exaggerate your "failure". Just as the others already said. If I was in your position I would probably feel similar. But from outside it's easy to see that that's just silly. I'm sure such a period of restraint and abstinence has taught you something useful, even if you are not able to recognize it at first. And you must also see: You are not alone. You are not a pervert. You are just not an anagami. And even if I don't really know you I would contend that you probably don't need professional help (from a prostitute or otherwise) but you were just exaggerating. My heart goes out to you my friend. I admire your honesty.
