When is they right time to say "I Love You". This is a very important group of words you need to say in a successful relationship. You might not say it at the beginning of the relationship. But, as your relationship develops, it usually gets emotional. I suggest you should say I love only when your conversation with her gets emotional or sensual.
When saying "I love you", you must have at least a reason why you say you love her. Tell her how special and important she is to you. Let her know you think about her all the time and give her a call at least twice daily. People enjoy feeling loved and wanted. Remember to speak those three words only when you get in an emotional conversation with your girlfriend. If you say "I love you" too early in the relationship, she won't be able to feel your love for her. If it's too early in the relationship, she would think it's not coming from your heart, so wait patiently for her till you begin having emotional or sensual conversation with your girlfriend.
You might be discussing something sensible and private with her and you feel a sensual overwhelming feeling that's the right time to say "I love you" to her. Saying "I love you" at the right time will appeal to your girlfriend's sexual desire at a deep primal level. -Be Fly, Classy & Debener
