TrUe LoVe

Being a new Christian is something all brand new. Its like riding a bike after not doing so for a long time. So when it comes to love, we all know that HIS love is amazing but what about the "earthly love"? When we get attention from the opposite sex,(especially the ones who aren't Christians like us) what do we do about it? Some of us try to bring them close to Christ, while others don't for the fear of rejection. So we turn a blind eye and have fun, but what do you do when the issue of sex come up?
Coming from living a life in the flesh and experiencing sex already is hard to turn down. How do I stay strong, and be an example to my friends?
