After you have the poem, you can try to find some ways to let him read it. You should not box yourself into just directly give the love poems for him. Be creative and there are many romantic ideas you can use. You could make your own card and decorate it beautifully with some embellishments. Then include your own written poem in the card. You could also write it on colourful papers. You can opt to insert it inside an envelope or do without it. Try to find and put at places where he is prone to go to around the house. Maybe you can put it on the dining table right in the morning where he will have his breakfast. You could also tuck it under his pillow and while he sleeps, he will be surprise to find written poem. Other than that, you could also pin it on the refrigerator. As he opens to take some food and drinks, he could see it.
You could also present your love poems for him on some special days. Events like wedding anniversary, first time both of you met and birthday will be a good time for you to pen and give these own writings of yours. The poems could go together with the gift that you plan to give to him. He will surely appreciate your heartfelt work and love for him.
