Relationship Advice- Show my boyfriend I am committed to him and Love him more than anything?

I wanted to do something very special for my boyfriend of 5 years. I want it to show that I love him more than anything and that I am 100% committed to our relationship and future. Some of the ideas I have thought of range from a sexy show to a billboard professing my love ha ha. Any creative ideas would be greatly appreciated! Thanks!

here is an idea: which doesn't involve dumb remarks like sex etc. Take him somewhere in the wilderness with a view to die for one that is 360 degree all the way around, big sky fantastic clouds if possible etc etc. get him to lie on the ground looking up and lie next to him and say " this is so big and so vast yet it doesn't compare with how I feel about you" sounds cheesy don't it but the surroundings the views the grandeur of what surrounds you will give him an idea of just what he means to you. If you can manage it take a half bottle of Champagne (you'll need a chiller to really cool the bottle down and insulate it well to prevent it warming up) with you and if you can two glasses engraved with your names wrap really well to prevent them breaking. Open bottle and drink the champers looking at the view. Done and dusted!
