Yes, excuse this term but it is a common feature of Bipolar during mania/manic episode.
I have never been fortunate to have much of any sex drive, may be due to me being more depressive than manic, I am DXed with Bipolar-II (mild) that may be another factor.
But yes, even in many books on Bipolar state that during manic episodes people may have a stronger sex drive, feeling more attractive, buying stuff, clothes, shoes, etc.
some sprees put many into debt.
Your therapist should be able to give you info on this, but my answer to this is "yes".
Hope this helps answer or give you insight to your question.

Take care now,
