This is so because Whenever a couple is about to get married, the custom of the Banyankole Tribe dictates that, and I quote: “The aunt of the bride first sleeps with the groom to ensure that he is potent” (that is to say in clear terms, that the Aunty of the woman that is about to get married will first have intercourse with the man that’s about to get married to her!!!.
To confirm if the man knows how to perform.
And it doesn’t end there, as the aunt still have to test the Bride to confirm her Virginity!!. In some cases, the tradition insists that it was the duty of the aunt to prove the potency of the groom by observing, that is, watching or listening to the couple while they are having intercourse.
