Being the Perfect Girlfriend can be quite a challenge. But with patience, It might JUST BE possible. Here are some tips to get you on your way.
YOU MUST RELAX YOUR STANDARDS. Let down your guard, and don't let etiquette be most important. This means eating like a pig (occasionally), burping, etc. Although things should be cleaned up in the end, the experience will allow you to feel comfortable with each other. That's the first important step.
DRESS UP SOMETIMES TO FEEL SPECIAL. This obviously is the opposite of step 1. Feel comfortable with each other, but don't get lazy. Dress up, and put effort into it. Look sexy for your man. He will definitely appreciate your effort, feel more attractive, and possibly want to return the gesture by putting more effort towards his appearance as well.
BE SENSITIVE OF YOUR MAN'S EGO. Although men will seem strong, our ego's can sometimes be delicate. Make your boyfriend feel good about himself through genuine compliments. Let him know you're aware of his efforts to improve certain relationship issues. And most importantly of all, communicate an idea; don't NAG about it.
ALLOW SPACE. A relationship is important. But so are his friends. He loves you but there are just some things that a friendship with the guys gives to him. So communicate to reach an appropriate agreement, and give him the space to balance out his relationship and friendships.
LISTEN. Men love to explain things. Sometimes even if you don't understand it all, try to keep an open mind. After all, he should be doing the same for you. These incidents shouldn't last too long, and he will be very grateful that you care enough to hear him completely.
THE WAY TO A MAN'S HEART IS THROUGH HIS BELLY. Good food is definitely a plus to becoming the perfect girlfriend. So try to make an effort to having a few good recipes. And if you don't know how to cook yet? Have a list of takeout places handy for just such an occasion. It's important because if we get hungry, we pay less attention to you (sorry in advance). So if you prevent us from getting hungry, our attention will be more focused on YOU. (which should be because you're almost the perfect girlfriend)
OVERTIME STEP: (NOT FOR EVERYONE). Bedroom Etiquette. Be mindful that a man's horny level is always around the same point as a woman's maximum horny point during period week. So now that you understand how we are, be gentle. If you aren't in the mood, gently let your man know IT HAS NOTHING TO DO WITH HIM (remember that ego). TIP: If you are not prepared for that stage of the relationship yet for whatever reason (religion, age, culture, etc), do not feel pressured to give in. He should/must respect your values.
Congratulations, You've completed the steps. You are (according to my books) the Perfect Girlfriend. Great job!
