I am proud of the marks my Master leaves on my body. I have some kind of mark the majority of the time, often on my breasts, stomach, thighs, ass and back.
I thoroughly enjoy the time he spends marking my body, the care he takes to ensure that each stroke of the cane or the whip is applied to a precise place. We have experimented with all kinds of "patterns" of welts, and even cuts sometimes if we use different implements.
I love the caress of his hand as he strokes my body after a session, as we talk about each welt. I especially enjoy the feeling of aching the following day as I go about my normal routine. It is a constant reminder to me both of the session and of my Master.
I am not shy of my marks, and wear clothing that shows them in suitable situations - whenever I can in fact.

I do have permanent marks. I have my Masters initials carved into my left breast. And I am more proud of that scar than I can express.
