Should I let him whip me?

My boyfriend has always been into a liitle butt swatting during our love making. I don’t really mind – I mean, if it keeps him happy and all. Then, last week, my birthday, he gave me a box. I must have guessed everything but what I got. I sure he must have noticed the shock on my face. He just laughed and said honey I think it’s time we spice things up. I havn’t told any of my close friends. The box had one of those riding crops (what horse people use I guess). I mean I’ve never done this before. A slap is onething. But insn’t this a whip? Won’t it hurt a lot? Will it scar me? I mean I’m kind of scared. There was one time that he spanked me until I cried. That was over a pair of jeans! Now he’s got this crop thing?!? The thing is I really love the guy. Any suggestions or answers to any of my questions would be appreciated.
