Love is in the air
There are several words for love.
η αγάπη love, generally speaking
ο έρωτας a passionate love
η στοργή a gentle love, family love
If the feeling is right and the timing is OK and you have the courage, you might want to say:
Σ'αγαπώ I love you
Σε θέλω I want you
For men: Είμαι ερωτευμένος μαζί σου. I am in love with you.
For women: Είμαι ερωτευμένη μαζί σου. I am in love with you
Μ'αρέσεις πολύ I like you very much
Λατρεύω τα μάτια σου! I adore your eyes!
Θέλω να κάνουμε έρωτα. I want to make love to you.
Είσαι ωραίος. You are beautiful. ( if you tell it to a man)
Είσαι ωραία. You are beautiful. ( if you tell it to a woman)
If you are in love but also you have time and money
Θέλεις να βγούμε έξω; Do you want to go out with me?
Ελα στο σπίτι μου, να πιούμε φραπέ! Come to my place, we can drink ice coffee!
Ελα στο σπίτι μου, θα σου μαγειρέψω ένα βραδινό. Come to my place, I'll cook a dinner.
Gentle words
Αγάπη μου, πάρε με αγκαλιά! My love, hold me!
Κούκλα μου, δώσε μου ένα φιλί! My doll, kiss me!
Μωρό μου, κάνε μου ένα μασάζ! My baby, give me a massage.
