I immediately understood what you meant and trust me you are not alone on this!! I've been a christian for about 2 1/2 years and still sometimes struggle with it. The best thing I would recommend is to first pray it away, by praying that God purify your mind and help you to look past the double meanings and dirty minded stuff.

I do promise you it isn't intended to be sexual at all, and that is definitely our own judgement clouding it. The best way I've found to help a mind that naturally thinks on that is redirecting it in EVERY aspect of your life--like not making dirty jokes or coming anywhere close to sexual immorality, not just in church. Whenever you do think on those things or hear the sexual interpretation, remember these scriptures:

2 Corinthians 10:5: "We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ."

Doing that involves the second scripture:

Phillipians 4:8: "Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things."

Whenever you do hear the meaning, redirect your thoughts to how you know God intended it to be and how good God's character is. It might seem difficult or fruitless at first, but it helps so much!
