Evidently bats understand just how important foreplay is when it comes to worthwhile sex.
Male flying foxes have been observed grooming their genital organ prior to mating attempts, leading to arousal. They will then approach a female who will give something of a chase, backing away for approximately a minute. The female will then stop and allow the male to perform cunnilingus before mounting her. After copulation is through, the actions of the male depend on which species of bat you’re observing. Some will resume cunnilingus, while others will groom their own genitals once more. The current theory is that oral sex is important for competition, as it can clean the genitals of a previous mate’s sperm, and it also leads to longer sex.
