If you weren't cut out for celibacy, God would not have demanded it of you. Yet, he has. Therefore, you are not only cut out for it, you were created for it.

So, the question then is, "does God demand celibacy from me?" The bible leaves no avenue for you to be anything but celibate. Therefore, the answer has to be, yes. Whether you feel cut out for it has little to do with it. If you were created for it, then you were created for it whether you feel cut out for it or not. Moses didn't feel cut out to lead the people from Egypt, but he had to do it anyway, no matter how inadequate about it he felt.
