Why this question? Are you indulging in incest already and now want a soothen balm to cool your self guilt? What you are asking about is an unpardonable abomination in Yoruba land. You are a son of Oduduwa, so I wonder why you are throwing up this issue. To answer you, the simple and frank answer is NO!
Dont try it because the repercussions of such an act can not be imagined even in this era of Christainity has cleaned up the past. If you doubt me, continue, it is only that I and the rest members of this forum will not be there when the sour/peppery soup will be placed for whoever tries it to lick. It normally brings everlating sorrow down the generations. Cousins as a matter of African (Yoruba) tradition must not fall in love with each other, they better sparead their tentacles of LOVE elsewhere. Good day.
WELL I WILL DIFFER HERE.FIRST IT HAS TO DO WITH CULTURE.IF YOUR CULTURE PERMITS IT,THEN GO AHEAD BUT IF NOT WHY ON PLANET EARTH SHOULD YOU DO IT?(AN INDIAN WILL NOT SEEV ANY THING WRONG WITH IT WHILE AN EKITI MAN WILL EVEN FROWN @ YOU MARRYING AN EGBA OR IJEBU GIRL)THINK WISELY COS A TIME WILL COME WHEN YOU B FACED THE CONSEQUENCES OF YOUR / OUR ACTIONS.
