Today at #LockdownBestiary, X is for X-rated. I cannot otherwise than offer up the final paragraph of Browne's chapter 'Of Hares' in Pseudodoxia Epidemica (1646). It introduces the words 'retromingency' (pissing backwards) and 'retrocopulation' (work it out) to English; 1/2
and ends in a mini Joy of Sex for the animal kingdom: 'nor is there one, but many wayes of Coition, according to divers shapes and different conformations'. Only humans however, he points out censoriously, try out them all.
@LockdownBestia1, of course.
