Here are a few options for the description of the WordPress post tag “性關係 (Xìng guānxi – Sexual Relationships)” in Traditional Chinese, ranging from more general to more specific:

**Option 1: General & Concise**

* **Description:** 與性相關的主題。 (Yǔ xìng xiāngguān de zhǔtí. – Topics related to sex.)

**Option 2: Slightly More Informative**

* **Description:** 涵蓋性相關議題的文章，例如性關係、性健康、性教育等。 (Hāngài xìng xiāngguān yǎnyì de wénzhāng, lìrú xìng guānxi, xìng jiànkāng, xìng jiàoyù děng. – Articles covering sex-related issues, such as sexual relationships, sexual health, sex education, etc.)

**Option 3: Focusing on Relationship Aspects**

* **Description:** 討論人際關係中關於性的方方面面，包括親密關係、性愉悅、性溝通和性健康等等。(Tǎolùn rénjì guānxi zhōng guānyú xìng de fāng fāng miàn miàn, bāokuò qīnmì guānxi, xìng yúyuè, xìng gōutōng hé xìng jiànkāng děng děng. – Discusses all aspects of sex within interpersonal relationships, including intimacy, sexual pleasure, sexual communication, and sexual health, etc.)

**Option 4: A bit more sensitive and inclusive (for broader usage)**

* **Description:** 有關性、性別認同、性健康以及各種人際關係的文章。 (Yǒu guān xìng, xìngbié rèntóng, xìng jiànkāng yǐjí gèzhǒng rénjì guānxi de wénzhāng. – Articles about sex, gender identity, sexual health, and various interpersonal relationships.)

**Choosing the Best Option:**

* **Consider your audience:** Who are you writing for? The more specific options are more suited for educated readers on the topics.
* **Topic coverage of the website:** Is your website predominantly about relationships or does it cover broader aspects of health and topics?
* **Your intended tone/style.** Do you want to be neutral or slightly educational?

I would recommend option 2 as it accurately categorizes a wide variety of topics, while being broad and useful for your website. You can refine or customize this description to best suit the content and style of your blog.
