Is it OK for a writer to ask for help with his/her stories?

I ask this because currently I have run out of ideas for my story and I need some help. I would have posted the so-far plot here but a few day ago I read a question of someone who had a similar problem to mine on Yahoo! answer. The best answer to it was: “A real writer should never ask for others’ ideas. Think it up yourself”. This has definitely discouraged me :( So is it OK for me to ask for help with my story, or am I not cut out for a writer because I have no more ideas for my story?
