Is it normal to dream of highly detailed sexual activities?

I'll start by saying I haven't had sex yet. Every once in a month or so, I get this highly erotic dream, where I'm present in a sexual activity. Every time it's something different, but it's always me with imaginary girls.
During these dreams I learn about sexual things regarding women, that I had never encountered in first person, such as the taste of a vagina or the feeling of women's sexual pleasure...
One time I dreamed of standing next to two or three naked white and perfect chicks. Long hair, something between brown and red, short, perfect pale skin, smallish breasts, somewhat submissive. They were making out. One of them sucked on the other one's juicy vagina. Then, wanting to taste it as well, she got up and approached me. She waited for me to lick the juices from her top lip. After that I think I woke up. I had the taste in my mouth for the whole day.
I kind of wonder if the dreams make me experience things as they are in real life, or if it's just my imagination.

Is it normal to have such details, teaching me the wonders of the other sex?
