Tokotoko, I know exactly what you mean. I'm just like you!
I'm an extremely caring and affectionate person and simply adore getting the same kind of affection and attention in return. It makes me feel loved and happy and that's how I express my love.

We should always be able to communicate our insecurities, fears and/or concerns in our relationships, and listen to our partners. Have you tried talking to him about this, in a respectful and calm manner?
