Be dependable. If you want to make your girlfriend want to have sex with you, then you should show her what an amazingly dependable person you are. If your girl is going to trust you enough to have sex with you, whether it's her first time or if she's had sex before, then she has to feel like she can depend on you. One of her fears may be that as soon as you have sex, she won't be able to rely on you anymore because you would have gotten what you wanted. So, prove her wrong by being an upstanding and dependable person.
Show up when you say you're going to show up. If you routinely pick her up half an hour late for your dates, she'll think that you don't think she's so special, and she'll be less likely to have sex with you.
Don't be a flake. If you say you're going to take her to the beach over the weekend, do it. If you don't stick to your word, she won't be able to trust you.
Be her rock. Let her talk to you about her problems and insecurities while knowing that you can make her feel better.
Don't go hours or even a day or two without returning her phone calls or texts. This will make her feel like she can't depend on you.

Give it time. Some people can be ready to have sex with a girl in the time it takes to down a beer, while some people can take months, or even longer, to decide that they're ready to make love. Some people are really adamant about holding out for the one, and don't even want to have sex before marriage. So, don't rush into it -- wait for the girl to trust you first.
If your girl is barely comfortable with kissing, then you shouldn't bring up sex for a while. However, if you and your girlfriend are already comfortable hooking up in bed all the time after just a few weeks, then you can start thinking about taking it to the next level.
If you want to make your girlfriend want to have sex with you, the worst thing you can do is bring it up or try to force it when it's way too early. This will turn your girlfriend off and will make her much less likely to sleep with you.

Do not act like you are obsessed with sex. Let's face it -- if you're someone who is desperate for their girlfriend to have sex with them, then you probably are obsessed with sex. That doesn't mean you have to make jokes, innuendos, or even blatant references to sex all the time. The last thing you want your girlfriend to think is that you're a person who is so obsessed with sex that you don't care which lady comes into your bed. You should make her feel special, like you want only her.
You don't have to hide the fact that you're a person with needs, but you should avoid being vulgar, talking about sex all the time, or talking about other people who have sex all the time.
Don't make derogatory comments about other women. This will make your girlfriend feel like a piece of meat. Remember that you're not with your bros, but with your special lady.

Be loyal. If you want to make your girlfriend trust you, then you have to be loyal to her. She'll probably never have sex with you if she thinks you're talking to or checking out other people. Though you don't have to be rude to or ignore other women, you should have a laser-sharp focus on your girlfriend so she knows that you will always be there for her, especially after you start having sex.
Spend lots of time with her. Make sure that you plan at least one or two dates every week and that you check in with her at least once a day if you're not together.
There's a difference between being loyal and being possessive and smothering your girlfriend with affection. You should make a point of seeing her when you both want to hang out, but don't try to see her 24/7 or she'll begin to pull back.
You should not only show your partner that you're loyal by being loyal to her, but by showing that you're a loyal sibling, friend, and family member. Show loyalty in many aspects of your life and your girl will be impressed.
