She should dump her boyfriend and find one who DOES do oral.
She should masturbate at least once a week so she can teach her boyfriend what to do with his hands. If he gets upset at the instruction, she should dump him.
They should go shopping for a vibrator and he should use it on her during sex. If he refuses, she should dump him.
She should just be patient and know that sex will get better when she hits her twenties.
