Boyfriend pointed out my stretch marks?

We've been together for almost 2 years now, and I'm actually pretty skinny, but right on my hips I have small stretch marks.

We were laying on the couch together and he was rubbing my waist (it wasn't feeling the best, slept on it wrong or something) and he says

"Scars. You have little scars."

And I said "What? Oh. God. No, those are stretchmarks." And I was just... really embarrassed.

But without skipping a beat he says,

"Well, no, they kinda look like you battled a tiger or something, there's four of them right in a row. They look like battle scars."

After it was obvious that I was still upset that he pointed them out in the first place and I was talking about how I hated them he started saying how he thought there was nothing wrong with them because they were on my body, and therefore they were beautiful.

I just don't know how to feel about this. I'm really self conscious about them anyway because they showed up during a growth spurt and never went away. I assumed he never noticed them and now that he has I just can't seem to get it out of my head that he's going to think they're gross and I'm a little hurt he pointed them out.

I just need a little advice on the situation I guess. :/

Interesting how the first few people who commented on this actually gave me a response that made sense, and then the minute today came everyone assumed that I was angry about it, which I never said I was.
