The most popular activity at an orgy involves a “man-woman-man” group: one man has intercourse with the woman “a tergo” while she bends forward to fellate the other man (cf. Martial 10.81; 67,84, 122,199,229,274.10; cf. 223,311). A version has Hostius Quadra, while being anally penetrated by a man and performing cunnilingus on a woman, exclaiming “I’m acting like both a man and a woman” (simul et virum et feminam patior, Seneca, Q nat. 1.16.7; cf. Williams 1999:255-9).
