Being sexually aroused is a normal thing in the life of every living thing.But what matters here,is how can u over come the urge of committing fornication which is sin.(1)The bible said, resist the devil & he wil flee.(2) The satan cometh to steal,to kill & to destroy.(3)Do not open doors to satan in ur life.(4)Avoid filthy communications wit the opposite sex,for bible said filthy communication corrupt good manners.Above all read ur bible always;Meditate on it day & night.The almighty GOD wil give u grace,to strengthen u in the area of ur weakness.AMEN!
