Sex and Attraction vs. True love

I never believed in what my horoscope ever said about what was going to happen. And the truth is I never will, but it's still interesting the things it says. The other day mine said "Don't confuse sex and/or attraction with true love" This was a really disturbing thing to read, being that my sex life was in the ruins, but still, I understand that I might be confusing them still. If anyone can help me with this I'd be much abliged. Just in case, I'm still not sure how to feel the difference...
