Fruit bats engage in oral sex

By in science

Part of the reason oral sex is rarely mentioned in the popular and scientific media is shyness about the issue. However, it may be more common in the animal kingdom than we realize. A recent study published in PloS ONE revealed that about 70 per cent of female fruit bats licked their partners genitals during sex. Interestingly, the licking of the female led to longer sex with each second of licking resulting in 6 extra seconds of copulation!

After the male mounts the female from behind, the female bents over and licks his genitals. The behaviour presumably favours the male bat. However, it might be that females engage in oral sex because they ultimately benefit. By the increased duration of intercourse, females may increase their success of fertilization. It may thus be suggested that manipulating the male by increasing sexual stimulation has important biological advantages.

Frans de Waal, a well know primatologist said:

“The Finding of fellatio in bats is exciting news.”

I cannot agree more!

    You may be surprised that DNA linked behavior is all mixed up in nature. Mother Nature makes the mistakes, not Father God. God is Truth, thus cannot be false. If it is possible it will come to pass. Nothing impossible happens — Truth. Nothing impossible is possible, and if it is, it is possible. TIG. (BTW: This is not sexist and I do not blame it on Mother Nature because she is female.)
