A woman went to her doctor for advice. She told him that her husband had developed a penchant for anal se*, and she was not sure that it was such a good idea
'Do you enjoy it?' The doctor asked.
'Actually, yes, I do.'
'Does it hurt you?' he asked.
'No. I rather like it.'
'Well, then,' the doctor continued, 'there's no reason that you shouldn't practice anal se*, if that's what you like, so long as you take care not to get pregnant.'
The woman was mystified. 'What? You can get pregnant from anal se*?'
'Of course,' the doctor replied. 'Where do you think politicians come from?"
