We all want to afford the 'large' one; to not have any money worries. I think that the biggest cause of marital stress today is money worries. Do all those adverts actually work? Some are so banal, it does make one wonder.
Personally, I like getting the best I can afford, in the hope it will last a long time. Although, I must admit, I've yet to go shopping for a dildo. How does one approach the sales lady, and request 'the large one, please'?
