Having affairs with slave merchants.
For fear of being captured into slavery many African women unwillingly had affairs with the white merchants and sailors. By having such affairs, they were free from being captured as slaves because they entertained the westerners on visits or transits providing shelter, sex and food to eat.
Despite being shunned and even disowned by their families, many young women chose this option than to be taken into slavery after hearing the ordeals that captives faced on the ships and plantations. If an African woman got pregnant for a westerner, it ensured her more security and protection.
