Obviously this question doesn't matter, as she was such a badass queen her reign was referred to as the golden age, but it's fun to speculate.

Do you think she was really a virgin?

I personally don't, the idea of a queen being abstinent her entire life is laughable to me, especially under certain circumstances like her people needing a heir so badly she was allowed to have anyone she wanted. But who knows, maybe she was asexual? There is several accounts of her behavior in situations that just seem too romanticized to me. Then again, she could have just been a drama queen (harhar).
