The baths are opened promiscuously to men and women. And there they strip for licentious indulgence (for from looking, men get to loving). It is as if their modesty had been washed away in the baths. Those who have not become utterly destitute of modesty shut out strangers. Yet, they bathe with their own servants and strip naked before their slaves. Clement of Alexandria (c. 195, E), 2.279.
We should not use the bath in such a way as to require a servant, nor are we to bathe constantly. Clement of Alexandria (c. 195, E), 2.283.
What of those [virgins] who patronize indecent baths? . . . They who disgracefully look at naked men and are seen naked by men—do they not themselves afford enticement to vice? . . . You make a show of the bath house. These places where you assemble are more foul than a theater. There, all modesty is put off. The honor and modesty of the body is laid aside along with the covering of garments. Virginity is exposed, to be pointed at and to be handled. And now, then, consider whether, when you are clothed, you are modest among men—after the boldness of nakedness has conduced to immodesty! For this reason, therefore, the church frequently mourns over her virgins. . . . Therefore, let your baths be performed with women, among whom your bathing is modest. Cyprian (c. 250, W), 5.435.
Do we believe that a man is lamenting with his whole heart . . . who from the first day of his sin daily frequents the bathing places with women? Cyprian (c. 250, W), 5.445.
Women should also avoid that disorderly practice of bathing in the same place with men. Apostolic Constitutions (compiled c. 390, E), 7.395; see also 2.282–2.283.
