The Qur'an explicitly talks about female virgins with large eyes as rewards for men. On the contrary there is not a single "women will get guys as a reward" verse. Some gender neutral verses do exist but they talk about general rewards only (such as "companionship" etc). Also, according to Shaykh ‘Abd-Allaah ibn Jibreen, who was a leading cleric and a member of the Senior Clerics Association, "This number is only for men. A woman will have only one husband in Paradise, and she will be satisfied with him and will not need any more than that."
"This number is only for men. A woman will have only one husband in Paradise, and she will be satisfied with him and will not need any more than that. The Muslim woman – who is not influenced by the claims of those who propagate permissiveness and knows that she is not like men in her make-up and nature, because Allaah has made her like that – does not object to the rulings of Allaah or feel angry. Rather she accepts what Allaah has decreed for her. Her sound nature tells her that she cannot live with more than one man at a time. So long as she has entered Paradise, she will have all that she desires, so she should not dispute now about the delights and rewards that her Lord has chosen for her, for your Lord does not treat anyone unjustly.",
