She smiled as he began to drink his tea, because that was good. That was a sign he was relaxing a bit. When he asked the question about rough sex, Lavender's eyes widened slightly. Oh, Merlin. She hadn't even gotten to explaining regular sex yet! "Okay... let me start with what I was going to say about regular sex first. Sometimes, after the caressing and touching and kissing, people want to be really close to the person they like, for both of them to feel very very good together. There are lots of different ways to have sex, just like there are lots of different ways to do other things, you know? There's oral sex, which is... when you kiss the other person's private area, or use your mouth to make them feel really good there. Or then there's regular sex, or intercourse. Both oral sex and regular sex eventually lead to having an orgasm, which is something that feels very, very good." How she managed to explain all of this without blushing, she wasn't sure. "Sex is beautiful, I think, because it's as close as you can get to another person that you like, to have them inside you or to be inside of them. It's different, depending on the people involved. If you want me to explain how different genders of people fit together that way, I can explain. I think if you've done it before, you might have some idea?"
Lavender paused to sip at her tea and then moved on to address his previous question. "So like I said, there are a lot of different ways to have sex. Mostly, this involves how there are a lot of different positions... it's kind of like dancing, these two people's bodies fit together, but there are lots of different ways to move their bodies to fit together, all of which feel very good. Some people like to be gentle and slow when they have sex, sometimes people like to be harder or faster, depending on how they feel. Rough sex is..." Lavender bit her lip for a moment. "It's harder and faster and maybe more aggressive, and it can involve pain, yes. But it's the sort of pain where you trust that the other person isn't going to actually hurt you, to the point where you're injured. It's about the trust, but some people also get pleasure out of the roughness, or the mild pain. It's hard to explain why they like it. It doesn't mean there is anything wrong with them, it just means that different people like different things. Like how some people like spicy food and other people don't. Sometimes, if someone asks you why you like something, you can't necessarily explain, you just do, you know?" She looked up at Colin and said, "You might decide you don't like rough sex, or you might decide you want to try it some time. It's up to you, because everyone likes different things. But you should never feel pressured to try something you don't want. Sex is sometimes best when it happens naturally, when it's a natural progression from touching to kissing to more. It's only fun if you want it, really."
