Would he be worth it?

I don't think you should go with your second crush. If he has already had with at least five girls at the age of 16, then he is going to have high expectations of you, maybe even end up pressuring you to do something you don't want to. So not only does it show that he doesn't place that much value on it, and is simply doing it for fun, but he is irresponsible, smoking weed and wagging school. Not exactly traits you would want a future boyfriend to have. As for your church crush, he sounds like a nice kid, but must you have a boyfriend at this age? Love interests take time and attention, and you could use those on your studies to get good grades and set yourself up for a nice future. You don't want to get so far only to drop down do you?
