When a girl talks about sex, it could mean a variety of things depending on the context and her intentions. It could simply be a topic of discussion, a way to express curiosity or interest, or a means of seeking advice or information. It's important to consider the individual's communication style, comfort level, and the nature of the conversation before making any assumptions about what it means.
[it means they want to have sex with you because they want to show their love for you]
Whoever said that is very daft about girls. If she's talking about sex it means she's thinking about sex in general. Not necessarily with you, or with anyone specifically. She could be just thinking about it in an intellectual sort of way.
It is sort of like when you talk to a girl about relationships, you're thinking about a relationship in general, not necessarily with her or anyone specifically.
She probably has no idea that talking about sex makes you think she wants it. Girls don't think that way. She wasn't saying that because she's flirting, or seducing you. Most women just don't think that way.
Another answer:
To whomever wrote the above 3 "paragraph" answer, if I'm talking to a girl about relationships, it's most likely because I want a relationship with that girl. So I would agree with the first answer in brackets that a girl who talks a lot about sex with you or hints towards it around you, basically wants you ESPECIALLY if she is flirting with you heavily (See Body Language Tips Online).
When a girl loves you she truly means it. When she talks about a boyffriend she doesnt like you. When she talks about a guy that is a friend it means she loves you and trusts you enough to talk about it with you without you getting hurt.
