There are many ways you can buy sex hormones from a reputable source. My best friend who is also a medical doctor sells these products on his website. There are several types of hormones, all of which have some effect on your sexuality. Some products are more effective than others. The more specific information on a product is usually provided in the manufacturer's product information, so I'll describe the types of hormones that are available. There are three different types of natural hormones: Testosterone: Most people are naturally testosterone-based, and they are the only natural hormones that are thought to affect human sexual behavior. Progesterone: Progesterone has many sexual side effects, but it is not thought to have much of an effect on sexual orientation. Estradiol: Estradiol is one of the female sex hormones, and some people who are naturally inclined toward girls will develop a tendency towards feminization. Testosterone and Estradiol are known as the "female sex hormones" because both are thought to influence the sexual development of females. Testosterone, the primary male sex hormone, is thought to make women more feminine, while estradiol, the female sex hormone, influences sexual behavior. This makes testosterone and estradiol very important for sexual orientation, since one or both can affect sexual orientation.
