If your gf is an anxious overthinker, tell her every sexual thought you have about her!! (Assuming you have a comfortable, healthy sexlife of course) it will make her feel more secure and desired.
Now imagine you're an apple, a pear, a plum, a strawberry, an orange, a cake, an ice cream, a pickle, cheese, salami, a lollipop, a cherry pie, a sausage, a cupcake, a watermelon, or a green leaf.
Not so happy, is it
