People say i have a hard time showing affection, but i really don't know how to. i try not to be so rude but i can't help it. what should i do?

Affection: You probably were not born with inhibition to express affection. Try to confide in a close friend and uncover the causes of your discomfort. Consult a mental health professional who can help you learn how to let go and express yourself without anxiety. Bst.

Expressing Affection: If you did not grow up in a home seeing your parents expressing warm/positive feelings toward each other, you, and/or siblings, being affectionate is probably foreign or unnecessary to you. Start slowly by greeting your close friends with a hug; holding hands with your boyfriend. The more you initiate physical contact the awkwardness will fade. The new behavior will soon feel natural. Enjoy!

Good idea!: Your heart's inthe right place. You need to learn lots more about people. I would suggest psychotherapy with that in mind, as well as group therapy with people your own age - that will help bring problems to the surface. You really can learn this. It may also be a great help to find out why it''s this way. Work hard ; good luck!
