Lois narrowed her eyes, but she wasn't going to push it. Plus the mental image of Clark's frowny faced self standing at Kara's door just made her laugh and shake her head. "Poor Clark," she said. "This has been so hard on him, but he's really trying to be a good sport. I'm sorry he's being so uptight about everything."
Pausing while she scooped up some salsa, Lois smirked a little. "Okay, so I promised Clark I'd talk to you about sex, and I have to agree that of the two of us, it's way better if I do it." Considering that pretty much everything Clark knew on the subject came from her anyway, and that he couldn't even say the word 'sex' without blushing. "But look - you're seventeen years old and I'm not going to assume you've been living in a vacuum since you got here; you're not an idiot and neither am I. But there's a lot of really stupid and wrong information out there, and you should probably have someone you can talk to who's not also a teenager, or an anonymous internet site.
"So, do you have any questions?" Lois' smirk widened. "I have never been one of these people who's uncomfortable talking about sex - to Clark, to kids, to anyone, so if you want a straightforward answer from an adult - no bullshit - I'll tell you what I know."
