Sorry, but originally, it was simply "desire" (i.e. in the original), and it is still written: What is born of the flesh, is flesh, and profits nothing - the mildest gentlest revelation that not what comes from the flesh is good nor helpful nor should be encouraged at all.
I am not certain of what you're saying. However, it is very important for people to understand that temptations are part of this walk with God. We are going to be tried and tested again and again -- and satan has much more to work with given that society is like Sodom and Gomorrah nowadays. Women used to cover their bodies, but no more and leave little to the imagination. We are indeed on satan's home turf, but we do not have to yield to him by giving over to lust.
To clarify, men and women are born with a desire for sex, just as much as we desire food to feed our bodies; it's perfectly normal because that's the way God made us. However, Jesus taught that when natural desire becomes lust (covetousness), then adultery of the heart has been committed. Satan has caused people to twist this Scripture to make them believe that they can't live free from sin. He will whisper: "you see, you can't live free from sin because you thought about it". It's a lie. You're being tempted, but resist the devil and he will flee from you. Cast down those unsavory thoughts, and proclaim victory as you resist sin by the power Jesus has given you. You're no longer living by the lust of the flesh but living by the Spirit. That's a Jesus over-comer. I pray that this helps. God bless.
