Sources would be nice. It doesn't have to be only America or someone well known.
And other historic figures like Valeria Messalina would be interesting even if he reputation is fictitious.
EDIT: quick google Empress Wu of china had male concubines (Concubinus)... not really what im looking for but similar... More like her and less like Catherine the great?
It is always possible to say more, of course, but in the meantime you might be interested in this previous answer, fully sourced, by u/Georgy_K_Zhukov.
