The Bible encourages romantic love! The book of Song of Solomon aka Song of Songs is dedicated to romantic sensual love.
"Let him kiss me with the kisses of his mouth—
for your love is more delightful than wine.
Pleasing is the fragrance of your perfumes;
your name is like perfume poured out.
No wonder the young women love you!
Take me away with you—let us hurry!
Let the king bring me into his chambers" -Song of Solomon 1:1-4 NIV
Sexuality within a marriage is beautifully celebrated in this book. It's like reading letters between a man and a woman who are deeply in love
"Your breasts are like two fawns,
like twin fawns of a gazelle
that browse among the lilies." -Song of Solomon 4:5 NIV
