Of course you want to be sexy and mature. It’s crossed the mind of every girl aged 13 to 15 at least a dozen times. You want people to take you seriously and find you attractive. Exhibiting authentic maturity and sexiness is an art that comes over time, but there are some things you can do now to help people begin to view you in an entirely new light.

Part 1 of 4:

Acting More Grown Up

1
Observe others around you. Find those people who you think are super mature and mimic their behavior. If you think your softball teammate is totally mature, act like her.
- You’ll know you’ve “arrived” when others start reaching out to you for advice or watching how you act in a certain situation.
- Relax, you will figure it out.
2
Take on more responsibilities. If you are able to land and maintain a real job, people will have to begin to think of you as something other than a little kid. Don’t go crazy with the hours as you should still be focused on having fun. Find something that will bring in a little cash but allow freedom for other personal activities.^{[1]

- Babysitting is always a good option. Find out who needs a little help once a week and land the gig.
- Think about tutoring a younger student. If you are exceptional at science, find out who needs help and put your talents to work for you. Watch everyone start to interact with you as a mature person, rather than a child.

Make friends. You are the company you keep. This means, if your current group of friends aren’t on your level of maturity and aren’t interested in the things you now are, it’s ok to make new friends. Find the group that you mesh with best.
- Be careful though as the older crowd may be involved in activities you’re not ready or comfortable with yet. It’s best to start hanging with your new friends gradually and feel them out.

Quit the whining. Only kids complain and moan and groan about every little thing in their life. Buck up. If you want to be seen as mature, start taking responsibility for your actions and outcomes. Plus, no one wants to hear it.^{[2]

- Skip the kid-like conversation and learn to express your emotions as an older person would. Say things like, “I’m really stressed about exams right now and need a break.” Instead of, “My life is over if I don’t get this new iPad.”

Acting Sexy

Exhibit pure confidence. Rather than wait on others to tell you how sexy you are, create a self-acceptance all on your own. Build a positive body image by finding what you love about yourself and fine tuning your self-esteem.

Skip the words. You can speak volumes with just body language. If you want to be sexy and mature, determine what works for you. Maybe it’s a subtly licking your lips, a cute wink or a full blown hair flip.^{[5]

- Be as natural as possible which may take some practice.

Be yourself at all times. If you are known for your wicked sense of humor amongst friends, then don’t hold back. Perhaps you’re blessed with an IQ that’s through the roof. Either way, people will think you are sexy because you are secure in who you are and are not pretending to be someone else.

Appealing to the Opposite Sex

1
Make the first move. Everyone would like to be the object of another’s affection and attention. If you are mature and sexy, you will have no problem approaching the person you spotted from across the room and striking up a conversation.
- Get creative as possible and skip the cliques unless you’re going for comedic affect.
- Flattery will get you everywhere. Be direct by telling them exactly what prompted you to approach them.
2
Be kind. Generosity is liberating and has a multiple positive effects. One, It proves that you aren’t self-obsessed and two, it helps someone else in need.^{[8]

- Give without expectations. People will see you as a phony otherwise.
3
Rock your natural sexiness. Skip the globs of makeup and tight revealing get-up. They want to see your naturally sexy eyes and shape.
- Always keep things age-appropriate. Though you want to be sexy and mature, you can do so without looking like a 35 year old. Your age is the best age and you only experience it once.
4
Tell the truth. No need to be brutally honest or hurt someone’s feelings, but everyone wants to know where they stand in a relationship (platonic or otherwise). If the person you’re interested in asks a question, be truthful.
- Use tact when doing this by softening the answer if you know it may sting. For example, lead with the positive by saying, “I think you’re an incredible person but I don’t agree with your political stance.”
- Never lie about your age. Be proud of who you are right now.
