[header] How to flirt with your boyfriend [title] Close the door when you're getting ready for a date. [step] Putting a (temporary) barrier between the two of you bolsters his surprise and delight when you appear gorgeously dressed and smiling. [title] Surprise him. <sep> (A) [step] It's your job as the host to keep his attention and make his day. [substeps] Use a fantasy wand to represent him in his pajamas. (B) [step] Making sure you're available to share ideas is a three-way street. Since he has nothing but his feet to cover, get used to the idea of taking the initiative to surprise him up front in the evening when he gets home from work. (C) [step] It may be as simple as buying tickets to a movie he wants to see or a pint of his favorite ice cream. Little surprises along the way brighten his life and break up the usual routine. (D) [step] Leave the door open if he'll be front and center in the doorway; if you're standing somewhere else, lock the door. As soon as he comes by, take a quick look into his range of vision; then pull him in for a sensuous kiss.
