A new once-a-day impotence pill that allows men to have sex whenever they want has been launched in Britain.
Cialis One A Day enables men to perform whenever the mood takes them.
Unlike Viagra or standard Cialis, men do not have to take it half an hour before having sex. It boosts blood flow to a man's private parts - but is effective only after he is sexually stimulated, reports the Telegraph.
The manufacturers, Eli Lilly, claims that the new way of taking the drug removes the forward planning needed with other impotence pills, like Viagra.
Cialis, also called tadalafil, is already available in the more traditional form but have now been turned into an "everyday" version.
Privately, the drug will cost 54.99 pounds a month, for 28 tablets.
There are also a number of side effects, including a headache or an upset stomach.
