I often see young girls stating that they prefer older men. And there's nothing wrong with that, we all like what we like. I totally understand where they're coming from, since some (albeit not all) older men have what younger guys lack, and what girls find attractive: experience, stability, maturity, etc. However, there are 3 things you must consider before jumping into a relationship with one, unless you want to be used and left with a broken heart. (Please note that I'm not writing this take to bash older men, as everyone is different, and there's lots of both great and shitty people among all ages. Besides, I'm currently in a relationship with someone who's older myself.)
1. Is he in it just because you're young and beautiful?
It is hardly a secret that guys prefer girls around their age or younger (and girls prefer guys around their age or older). Of course it's a generalisation, and there're exceptions to his rule, but in a grand scheme of things this statement is more or less true. But then there are also shallow men who only want young and beautiful women. You will not a person to him, you will be his trophy and sex toy. He will feel proud of "landing" an eye candy like you. Dating someone young and beautiful will stroke his ego. Don't set yourself up for such treatment, you have to really ask yourself whether he likes you for your personality, or just your exterior. People would usually want to date someone similar to them, if you have nothing in common, chances are he's just using you.
2. Does he only pursue you because you're inexperienced?
It all boils down to "everyone wants to date someone who is similar to them" once again. If there's a big age gap between you, not only your interests may differ, you may simply be not mature enough for him. Of course there are very mature young people and extremely immature adults, but this is a rare occurrence, and usually you and him will simply be on very different levels when it comes to maturity. As smart as you may think you are, if you are young, you lack experience and are probably easy to manipulate. If you know that you two are at different stages of maturity, a guy and yet he still pursues you, stay away from him, expecially if he can't get any women of his age to date him. They probably avoid him for a reason.
3. Do you two share the same values?
You may want a romantic relationship with someone who loves and adores you, while he may be tired of the whole relatonship game and just looking for a hook up. He may be old and mature enough to want to start a family and have kids, while you would prefer to enjoy your best years without such responsibilities. Or maybe you do want kids, and he thinks he went that long without a family and kids, so no reason for him to have them now. His generation may have a different outlook on things than your generation does. In short, there are many possible options, so you have to make sure you two match when it comes to this.
To conclude, not everyone is nice as they seem, There will be people who are only out there to use you and hurt you, but that's not a reason to deprive yourself of various experiences. Go out and make mistakes, life is not always going to be smooth and drama-free, just remember that it's up to you be careful and look out for yourself, because sometimes nobody else except you will. Good luck! :)
