Well...

-The etching in the first folio edition of Shakespeare's plays, published in 1623 (7 years after his death), is generally agreed to be the nearest thing we have to a contemporary likeness.

And yes, he really did write all those plays (including "The Two Noble Kinsmen", in collaboration with Fletcher). And all the sonnets, too.

-While we can never be entirely certain what she got up to *before* becoming Queen, it's un-bloody-likely that Elizabeth I ever had sex during the entirety of her 46 year reign (and that's a loooong time, folks---she might as *well* have a virgin at that point in any case!). For one thing, the very notion of personal privacy out of the question for a person in her position (who literally had some one appointed to hand her the 16th C equivalent of toilet paper, and they counted themselves fortunate!)...any number of people would have known about any sexual activity, and AT LEAST one of them would have sung like a canary to SOMEONE. She was also all too aware of the risks inherent in allowing herself to become emotionally attached to anyone: while her affection for Dudley is indisputable, she knew it would be impossible to marry him without causing enormous factional dissension at Court, and after Amy Robsart's death it became completely out of the question. She was also always at pains to distinguish herself as "a prince", and to be taken seriously in the political arena; an alliance with anyone would have undermined her position. Additionally, she would never have run the risk of---God forbid!---an accidental pregnancy; her attitude towards ladies in waiting who became pregnant out of wedlock is enough to illustrate her feelings on that point.

-While Henry VII certainly the motive to play the villain in the murder of the "princes in the tower", he had nothing like the opportunity or immediate necessity that Richard III had to be rid of those boys. While history has often chosen to overlook the fact that he was in many respects an able administrator and a relatively just ruler during his brief reign, the fact remains that he was in all likelihood responsible for ordering and/or arranging his nephews' murder.

And those are the only of the above burning questions which I'm presently qualified to answer with any authourity!!
