How do you get your girlfriend to take off her shirt?

First See how sexy agirl is and always try to be close to her and try that she herself first kisses u if so u become ready and call her alone two or three times and in last turn she herself will want u to be sexual with her . To get started sit close to her and say that she is very beautiful and u will see that if she gave a smile than u can do every thing with her. Hint:always be confident and before doing some thing sexual with her u have to witch is neccessary hug her and your one hand should be on back side of her bra and other should be near to her neck and your head should touch her head and this would perfectly work but remember to be confident.
