LTR vs. playing

I have a strong internal conflict that is hard to fix. My father, friends, etc. keep telling me that I'm young and I should just be going out and having fun, and when I am out playing and see a pretty, fertile young female, I do want to sleep with her. However, my heart really just wants an LTR so I can come home to someone every night and cuddle up with them. This is painful because these interests collide when it comes to PU. Perhaps I will be able to find MLTRs where I can always have someone to call upon for sex or cuddling and watching movies, but I won't have to worry about the emotional drain that can be a single LTR?
