It's absolutely normal to have dreams about sex, so don't freak out. Most people have them, and in fact, some people (both male and female) even have nocturnal emissions while they're sleeping, which is commonly known as a "wet dream." But yes, it's normal, and nothing to be embarrassed about (unless, say, you have a dream that you are making out with Simon Cowell or something!).

Actually, some experts think that there are times when sex dreams aren't even about sex. In other words, they might be about how we see other people or how we think they see us. That's why sometimes we might have a sexual dream about someone we aren't really interested in in that way. Just because you're dreaming about kissing someone from your third-period math class doesn't mean that you want to go up and do it for real; it may just be your mind's way of working out some other sort of problem or challenge in your life. Dreams are so confusing because they speak to us in metaphors, not logically the way we're used to doing during our waking hours.

Even if a sexual dream is about sex, that's still not an indication of what we choose to do in our waking, conscious life. You will know when you are ready to be sexually active, and it's not because of a dream you had!
