Hook up/one night stand

Rebecca • 17. Getting ready to be on my own. Trying to live the best life I can while battling depression.
So I'm gonna hook up with this guy tomorrow and then I leave for college the next day. But I'm hoping this will be like fuck biddies when I'm in town 😂 So any ideas what to do to keep him wanting more? Any ways to push past that initial awkwardness?
