Flirting and Fun:
Get a regular schedule of working out with resistance exercise and aerobics. Also do not overeat, and watch your caloric intake. Take necessary supplements, such as a multi-vitamin/mineral.
You will start to feel more comfortable in your own body, giving you more confidence in yourself, whether the opposite sex approaches you or not.
This will help you feel better about life, no matter what happens. This factor alone will make you more attractive.
