Enjoyable flow of imagination of a jovial and funny good fellow. Both author and poetry are enjoyable and may keep high mood.I do not know if you really studied at the light of a candle or is just a poetical figure of style. Also, in a church or cathedral there are fired many candles to see the Light. Amazing and amusing, indeed.

the great joy of growing very old is at last he was free from lust, and could finally think without this impediment.I think he called it his "hunchback". I am getting old, but not reached that yet! Or, as Schopenhauer said a few hundred years ago, until the age of 35 a man is a giant penis. He spends the next 35 considering his demise and ultimate death.

Your poem is nicely crafted. So whereas I sympathize with you, I might suggest you follow your passion a bit and enjoy the feeling of lust and seeking courtship. It's what all the singing of the birds is about. There will be time to sit by the fire...although written about a woman, Yeats put it perfectly

When you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep;

One day you will be free. Today, go rejoice in the dancehalls of your dreams.
