Answer

To answer the question, "Sexual characteristics that are present in a person since the time of his/her birth are called _____ sexual characteristics," we can follow these steps:

1. **Understand the Types of Sexual Characteristics**: There are two types of sexual characteristics: primary and secondary. Primary sexual characteristics are those that are present at birth, while secondary sexual characteristics develop during puberty.

2. **Identify Primary Sexual Characteristics**: Primary sexual characteristics are specific to each gender and are present from birth. For example, in males, the primary sexual characteristic is the penis, and in females, it is the vulva.

3. **Differentiate Between Primary and Secondary**: Secondary sexual characteristics appear later in life, typically during puberty, which occurs around ages 12-13 for females and males, respectively. These characteristics include features like breast development in females and facial hair in males.

4. **Conclude the Answer**: Since the question specifically asks for characteristics present at birth, the correct term to fill in the blank is "primary."

Thus, the complete answer is: Sexual characteristics that are present in a person since the time of his/her birth are called **primary** sexual characteristics.
