The following is a review from The Daily Mail. Sadly no penis it seems.
”Smith features in both the sex scenes that punctuate early episodes. Viewers who grew up with him on Doctor Who should be warned that one shot reveals a naked Daemon, from behind, with his pink rear looking like two slabs of pork on a butcher's counter.
His friend, whose favours he has purchased, notices his lack of enthusiasm. 'What troubles you, my prince?' she trills.
When he turns around, careful camera angles hide the worst, though this attempt at modesty has an unlucky effect: Matt appears to have no genitalia, like Barbie's friend Ken.”
