I say, why not? The government already tells you what to eat and drink, what to say and think, what to learn or not, what is good for you and what not... So telling you how to fuck and when is just another logical step.
Actually, it may not be that bad. All you have to do is to get a written consent from that girl, have it signed by by several appropriate public figures, get it approved by her father and/or mother, get a couple of stamps on it to make sure that it is legal, and she is all yours.
I would actually add a videotaped consent with time stamp to it. All the girl has to say is: "Yes, I want to have sex with [your name, date of birth, social security, address] on [appropriate date and time], at [approved facility, exact location, must be spelled correctly], with estimated length of fucking act lasting [state number of minutes] and under supervision of qualified legal adult [father's date of birth, address, social security, current location and phone number].
And, if the government is really smart, they would add fees to it. For each fucking consent only $15 fee. Non-refundable, should you change your mind. That way it would be impossible for the whole country to go bankrupt, because people will simply be fucking till the very end of our society.
Imagine, after she signs and reports her intentions to fuck your brains out into your iPhone camera, she can say as many "No" as she wants - but you will always have a proof that you did the right thing...
