Whom/How to ask for a college recommendation letter?

Was it wrong of me to ask my professor for a letter of recommendation?

• Here's my situation: I am a college student, considering transferring to a larger school. I intend on staying at my current college, but I figured I would apply to another school just for the heck of it. Why not? I am at the top of my class and am well-liked by my professors. I am my favorite professor's best student, and he has done much for me, from creating a scholarship for me to going out of his way to help me get an internship. In order to apply to this new school, a letter of recommendation is needed, and I asked my favorite professor to write me a letter. He said he would happily do so. Was it wrong of me to ask my professor for a letter of recommendation? I am afraid that after all he has done for me, letting him know of my intent to apply to another school could have been insulting to him. By letting them know I'm considering transferring, do you think I have ruined my relationship with my professors?
