Africans will always react to people with other sexual identities because we haven't evolved to the point of acceptance. Our values are always considered as number one there fore it will always be difficult to conform to the new normal.
For now, other sexual identities have not been legalised or passed into law so it will be tough for whoever is pansexual to be accepted since they lack legal backing as well.
Until such sexualities are passed unto law and declared legal in most African countries, whoever identifies otherwise should conform with the norm of this society or go to places where they'd be protected by a law that suits their sexuality.
