Indeed. In modern times, the celebrated castrati of the operatic and clerical music world were quite famously sexual.
Because the practice of castrating boys to maintain their high singing voices (thankfully) ended by the late 19th century, most of us have forgotten Europe’s very recent experience with eunuchs.
But it doesn’t take much a dive into the literature to understand how sexual many of them were. Nothing about castration cuts off the possibility of a sexual life.
In the ancient world, eunuchs were often slaves, castrated not to make them less sexual, but to prevent them from impregnating their masters’ wives and daughters when they did have sex.
In some cases, eunuchs were created because their masters wanted to preserve their boyish looks, for sexual purposes.
No one in the ancient world would have read a reference to a eunuch and considered that it referred to a non-sexual person.
