There is sex which God created, and lust which God did not create. There is no reason to hate the good thing that God created. If the lust is driving you crazy, and not bringing you into intimacy with God and enjoying God, it is a trick; that lust is what is not loving you, then.
And with a really Christian lady, your love is more enjoyable than just physical sensation and her outward beauty. So, it is good to grow in love and not fall in lust. Learning how God has us love is so much better and more enjoyable.
In case you have gotten hung up about sex, it is possible you have not been feeding on things God's word gives us about how to love in a close relationship. Can you tell me scriptures which help us to find out how to love the way God wants? Or, has your attention been getting tricked??
Lust is a trick; it can not be satisfied; yet, it promises how you will be satisfied if you do some thing. But that is a lie.
But God deeply satisfies us in His love while we are doing what He shares with us. There is intimacy better than sex, and personal and deeper because this is found in God's love. So, discover people who help you to this
And you can get ready for a real marriage, by praying and feeding on God's word, instead of feeding on other stuff.
Any part of the Bible can be used by God to help us with this.
Here is one example >
"be content with such things as you have" > in Hebrews 13:5.
For me, this does mean to be unconditionally satisfied with God, so I can be content with whatsoever I have. I can share with God in His peace, and this peace is better satisfying than any physical nice thing I have ever enjoyed. God is better and kinder and more satisfying than the good things He has made. Plus, they can't love me!
So, if I am love-satisfied, lust can't get the better of me.
And so, I do well to be first satisfied with whatever I have with each person . . . not demanding and feeling entitled and trying to use people. Be thankful to God, instead, and trust Him to decide and guide what I enjoy in each relationship . . . quality, if not quantity.
And I understand this works well in marriage or any close relationship > even if I have a special person . . . or special people . . . do not suddenly feel like they owe me something and have to give me the time and attention I expect, but be appreciative of how ones really are ready to share with me. Appreciate the time and attention they do trust to me.
Because any for-real Christian lady has various people she loves and cares for deeply. So, you are wise to be in touch with her loving, and not where lust would take your attention.
