First, male friends can enlarge the reproductive system of penis. When your penis is not erect, hold the glans tightly (but be careful not to cause pain), release it after 10 seconds, and repeat 10 times. Make an elongated rotary motion, clockwise and counterclockwise ten times each. From this, you will feel a partial erection of the penis.

Secondly, female friends have much smaller breasts. In order to be beautiful, we can transform the reproductive system of the chest and do breast enhancement surgery to achieve the ideal effect.

Third, some boys really want to be women, that is, they have abnormal sexual orientation or "transsexuality", so that they can have plastic surgery and achieve the goal of transforming the reproductive system.
