Is it weird to ask for my teacher's number?

Airii
So I'm graduating today, and I've been wondering for the last few days if I should ask for my psychology teacher's number next time I visit him. I'll be visiting him often since he expects me to seek out certain things and report back to him—not for romantic reasons. So I must know, would it be strange for me to ask for his number for convenience sake? I find it a bother to keep in contact with him through email exclusively.
