Having a hot girlfriend is different than having a not-so-hot girlfriend. If you're like me, you have been out picking up women for a while, but found someone that's just so awesome, cool, and attractive that you decide to make her your girlfriend. This guide is about what to do AFTER you get the hot girl to agree to be your girlfriend. I haven't seen a lot of guides on how to handle this situation, so here's my stab at how to keep her attracted and keep the relationship flowing smoothly. It includes some observations I've made, but feel free to add your own:

• Don't be needy. Ever. Even for a second. Hot girls can sense neediness and they respond negatively to it. This is especially true when you're in a relationship with one. Don't beg to spend time with her, don't fish for compliments, and don't call/text too much. Give her space; this shows her you are secure in your relationship, and she will respect you for that. If she decides to travel or go out with friends without you, let her do that, and go do your own thing for a while. If you aren't with her and you feel yourself getting needy, leave your phone at home and go do something without it for a few hours, even if it's just going for a run or going to get a beer by yourself.

• Continue to demonstrate abundance and value. Have lots of friends that you spend time with. Provide value in every situation. Make memories that you can share.

• Don't let her be your purpose. She's there because you're a complete and centered person, that's what attracted her to you in the first place. Don't let this slide. Have hobbies, business pursuits, passion for something besides her. This will allow you to keep her respect.

• Other women will hit on you when you are with her. Often, this will occur when a woman comes up to you and says 'your girlfriend/date/friend is really pretty,' or something similar. To be clear (and it took my girlfriend to point this out), this is not them hitting on your girlfriend, this is them hitting on you, albeit indirectly. Women, especially ones less attractive than your girlfriend, get insecure, and they will try to put chinks in your relationship armor. Don't let them do this. Deflect and ignore, but be cordial and maybe set them up with your single friends if they're around. Having a hot girl with you conveys loads of value and women respond to this, it's their nature.

• Men will hit on her when you are with her. You need to step up to this. Most of the time, the dudes that hit on your girlfriend will be total chodes and it's likely that your girlfriend has been dealing with these types for years. She knows how to handle / deflect them, but if they get annoying or clingy or creepy, you need to step in and make some kind of move, physical or verbal, to indicate she's with you. Be the alpha and befriend, ignore, or tool on the guy (tool on him only after you've tried the first two). However, be on the lookout for a signal from her (especially panicky eyes that are scanning the room or looking straight at you - it looks reactive). If you see a signal like this, step in right away. One time, I saw this happening and literally pushed another girl we were with between some dude and my girlfriend (in a playful way). The dude backed off instantly and my girlfriend came up to me and I got a very appreciative makeout.

• A hot girlfriend will test your testicular fortitude on a frequent basis. For me, this usually comes in one of two ways. First, she will make some snarky or bitchy comment to undercut you in a small way. Not a mean comment, but something borderline funny/snarky/bitchy to see how you respond. You can do one of three things that seem to work to keep her respect and keep her knowing you are in charge and centered: a) ignore and don't respond - change the thread entirely, b) reward her in some fashion - a kiss, a squeeze of the hand, a smile. Choice (b) may seem ridiculous and counterintuitive, but it works, I promise. Getting rewarded for being bitchy short circuits her brain: she doesn't get a negative reaction from you (in fact it gets a positive one), so she realizes you aren't affected or made insecure by her comment, so she backs off and doesn't do it again.

She can also test you by trying to get lots of things from you. You have to draw a line in order to show you are not a pushover. Be nice and do things for her (she's your girlfriend and you - presumably - care about and respect her), but don't be too nice. It's a fine line to walk. Let me give you an example. My girlfriend wanted a ride home from a work event, and doesn't have a car. I agreed to pick her up. She later asked if I would take her two interns to their respective houses, kinda far from where I live. I straight up said no to this, but agreed that I could give them all a ride to a bar after and we could all hang out. Nice, but not too nice.

• Show her off and be proud to be with her. Most guys never get girls like this. Take her out dancing, to bars, have her meet your friends. This lets her know she's important to you and keeps her in the social loop. She likes being out and about, I promise.

• You don't need to buy her stuff. Buy a drink or two when you're out, but you should be equal partners in who pays for things. If the expectation becomes that you pay for dinner, then you become the guy who just has the hot girl because he has money to spend on her. If you travel together, you get the flights, she gets the hotels, etc. Give gifts sometimes, but make them meaningful and spontaneous. If you are a pushover and pay for everything, she will lose respect.

• Tap. That. Ass. Seriously, she loves sex and you should be doing it frequently, improving your skills at it, and figuring out how you can have better sex together. Dominate sometimes and do what you like doing, but be sure to keep her satisfied. No one ever broke up because the sex was just too good.

• Overall, keep it spontaneous and fun, but with a punch of drama once in a while. Women don't just like the super happiness bit all the time. Once in a while, a little drama doesn't hurt. Doesn't have to be anything serious, just something where you come off looking awesome. For example: we were grabbing the last train home the other night, she was able to get on and I, (two seconds behind her) got the door shut in my face. I literally screamed at the conductor to let me on, and he did, I got on the train with my hands in the air like Rocky and I made out with her in front of everyone. The entire train was cheering (this was a 1:30 train home from the bars). Be her champion.

• If she fishes for compliments, don't take the bait. She gets enough positive reinforcement (especially about her looks) elsewhere. But, offer up spontaneous and serious compliments that you truly mean. If she acts a way you like, tell her. If she's being bratty, treat her like you would treat a bratty little sister.

• Improve yourself and encourage her to improve, she will respect and love you for it. There's always a harder workout to do, a run you can go on together, a new skill to learn, a new activity to try.

I'm sure this guide is incomplete, and my only disclaimer is that some of these things only work for VERY hot women. Minimum of a 9 for some of this stuff. Otherwise you're just going to end up hurting her emotionally. Some women who are very attractive have never heard a negative thing in their life, and rarely get told 'no.' You're going to be the guy that doesn't put her on a pedestal. Do this, and she'll stay attracted to you for the duration of your relationship.

EDIT: BadGirlThrowAway brought up a solid point, and I want to clarify. Don't confuse neediness with being emotionally open. These are two different things. Being emotionally honest in a relationship is vitally important. Neediness ruins relationships, emotional honesty sustains them.
