Actually, your subject line tells a lot, as well. You're not ready for this type of dream to become reality - and you are perhaps uncomfortable admitting to the fact that you may be experiencing such dreams.
As much media as you may be subjected to, I would guess that this is what this dream stems from - and you are wondering at how you would handle such vulnerable activities. You may be ready to explore the next step to adulthood - and acting out in your dreams has "awakened" you to these possibilities.
Just be careful out there.
