The Poetry Foundation has posted a selection of love poems on this page, which I would encourage you to read, and if you're feeling particularly sporty today, to share with someone you love. Far and away my favorite work, however, is Stanley Kunitz's "Touch Me," which, sadly, is not listed by Poetry.
Kunitz delivers a powerful and compact mediation on life and love in the brief poem, which concludes with three stunning and plaintive lines that issue from the preceding meter with a naturalness that catches the reader by surprise. Read it and see if you don't agree. A Pulitzer Prize winner and Poet Laureate, Kunitz produced his best work much later in life - "Touch Me," for example, was written at the age of 90.
And give someone you love a hug today. Tell them how you feel.
