The most frequently offered tip from sex experts is that, when writing romantic letters, just be yourself.

Paint a vivid picture with your words. People who want to learn to write romantic love letters need to become more specific in their writing. Sex experts agree that vague, sentimental platitudes have no place in a romantic letter. Instead you need to come out and say exactly what you are feeling and describe in explicit detail what you would like to do with your partner.

Reflecting on the difficulty most people have with passionately expressing their love for another person, a prominent sex expert recently stated, "Most of us are trained to be repressed. We are so scared to show our true, burning, passion, because it is not accepted in our society." Writing a romantic letter requires the writer to set aside shame, fear and repression, and instead embrace his or her inner lover.

Be erotic: remember that true, passionate, love is not just all about roses and chocolates and teddy bears. The passion and desire two people can share is one of the most beautiful things in the world. So don't censor yourself when you write romantic love letters -- instead, try to reach down into your pit of burning desire and let it flow onto the page.

Finally, you might try including a little something extra in your envelope. Deep red rose petals, a lipstick-smeared kiss, or an object that will remind your partner of something special you share are inspired ideas. Some sex experts recommend enclosing a photograph of a special time together in order to inspire your sweetheart's romantic memories.
