Is it normal to want to be a woman's "bitch"?

I'm a 27 year old straight guy that's been turned on by female domination since I was about 12. I've never been in this type of a relationship but always wanted to. All the chicks I've dated were I guess you could say "normal". I have fantasies of an older woman making me her slave, putting a collar on my wrist and putting a leash on it when she takes me out in public. I want her to take me into Victoria's Secret and pick out some panties for me to wear. I want her to peg me. I want to be her little brat and her to spank me when I misbehave. It's not just sexual, it's also a physological and emotional thing. If I get married I want to take her last name.
