James, my man, put the brakes on this. I know that your 13 and you have all these feelings you probably have never felt before or know what to do with, but you have to be smart about this. Sleeping in a bed with someone when she isn't your wife is not a good idea. The bible tells us in 1 Corinthians 6:18 "Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body." I don't know what your intentions are in this...,whether you just want to cuddle with her or your looking to be intimate sexually with her but either way, you are setting yourself up for sin. By sleeping in the same bed your are literally handing the enemy a loaded gun. The bible tells us in James 1:15 "Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death." I promise you that this feeling of wanting to marry her is a feeling you will have for plenty of other girls through your teen years. I can almost guarantee that a girl who would lie to her parents about you being gay is not the one for you. You have your whole future of crushes and girlfriends and if your called to marry by God, a wife ahead of you, please don't do anything that will thwart God's plan for your future. Jeremiah 29:11 " For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future." Hold on to God's promises my friend, and he will not lead you astray.
