Hey, Cool,
Did you ever stop to think that, you don't hear from many people here, because to most, your dilemna is no big deal. I don't mean about you as a person, but the situation you're beating yourself up over. It's not unique or original I can assure you of that. I also realize, that knowlege doesn't really help you find your way out of your wilderness. You will get this solved in a way that works for you.
Honestly I haven't read the first 2 threads, but I saw that this one was related to the perv thread and went back to read that one. Don't think I'm defending Sabutai against you, I haven't read everything, yet, but what I read in the perv thread was nothing more than a jolt of reality check and tough love from him. He could certainly have chosen other words to use, but what he says is true to some degree. If you are really having this much anguish over the situaton then you already have your answers. Follow your heart, balanced by your conscience.
No one is thinking less of you for a flesh (weakness) response to a blood (strength/bond) relative, especially a cousin who is not exactly the same as you genetically. Of course cousins marrying has happened in the past with high profile people and it was somewhat acceptable back then. Obviously it would be a strange family that would condone such a relationship, in these modern times, and that doesn't make the flesh any stronger, but the blood bond of the rest of the family is already speaking to you. Let go of the guilt if it's too much to bear and get yourself out of the situation that has started the stress.
On a side note, I've had crushes on 2 cousins before. MrMark mentioned having 31 cousins, but I have almost that many on each side of my family, and some are really pretty. I'm an old fart now, but I can still remember being a little unsure of myself and even getting so close to the point of no return that I lost all caring. I never took it all the way as we used to say, but we were in danger of doing just that on more than one occasion. How far we went is not the point, though. The fact is that our flesh is weak (as they say) and desire is powerful, enticing and hard to resist.
I still share a very strong relationship (closeness, not sex) with one cousin, but we are both married, she's got grown kids and I've got young ones and we live a thousand miles apart. We exchange phone calls, pictures, and Christmas cards. There is always a little extra effort put into hugs we share, in the rare times when we do get a chance to see each other, which is usually around a funeral now days. That's as far as it will ever go and I have no regrets having that kind of special love for the woman.
With the other cousin, the closeness, caring, and special bond never developed, but the sexual attraction was certainly there, mutually, when we were younger. It was just one of those white water moments that life has thrown my way at different times.
No one thinks less of you, for being human. Starting 4 threads is an indicator that you need to take action. Dig this thing out of you like it's a splinter, get free from all this anxiety you've been cultivating and move on past it. Start soon, before it's too late.
