My minds telling me friend, but my dreams telling me sex

I'm fairly young, only 16 years old. I've been in a relationship with someone I really love for almost 2 years, not once have we doubted each other and have worked though every bump in our confusing teen lives. Though this problem I don't fell comfortable mentioning to him recently as the months passed his friends became my friends. Everything's been fine until a couple of weeks ago I've experienced some lewd sex dreams about his friends. I acknowledge some I see are attractive but I have no emotional or sexual feeling or intentions twords them otherwise. I've never even had sex before. I know that this won't be the straw that broke the camel's back in our relationship but this is still something I'd prefer to keep to myself. We have both discussed similar situations and have come to the conclusion that we have little conscious control over our dreams and will not hold each other responsible for them. What I would wish to know is if there is a good reason for these dreams? And how do I get them to stop?
