性器英语怎么说呢

性器在英语中通常被称为"genitals"或"reproductive organs"。

"Genitals"来自拉丁语"genitalia"，意为生殖器官。

"Reproductive organs"意为生殖器官，这是一个更正式的说法。

例句：

Male genitals include the penis and testicles. 男性性器包括阴茎和睾丸。
The female reproductive organs are located inside the pelvic area. 女性生殖器官位于盆腔内。
The genitals are a sensitive part of the body and should be handled with care. 性器是身体敏感部位，应该小心处理。
