Right after I cum after having sex with another man, I don't have much desire to have sex with another man. Actually, right after I cum, I want to go to sleep. ;-)
I think the fluidity of one's sexuality has to be taken as what it is. The only part of the OP's post that disturbs me is his seeming elation. "Yes, I don't like cock anymore!" I mean, if you were troubled by your bi-sexual urges and wanting to get rid of them, maybe you've successfully done just that. You want some sausage, and now you've had your fill.
I would just caution you that you may find the hunger again. How you deal with that is up to you, and I'd encourage you not to beat yourself up about it too much. (Maybe you're younger and don't carry the baggage most of us over 40 guys do about same sex attraction.)
BTW, I had several years where I did not need or particularly want sex with another man, but that changed once I wasn't stressing out about job stuff and I actually had an outlet via the Internet. I can repress with the best of them, but it all came bubbling up to the top eventually. (Hey, did you see how I worked in "came" and "top" into that sentence without really trying. Sheesh, I'm too juvenile by half sometimes. heheheh)
