YES says Kelly Rose Bradford, 40, a journalist and broadcaster from London
When it comes to willies, people love coming out with the diplomatic phrase: "It's what he does with it that counts." But, let's be honest, a little acorn is simply not going to reach the same parts that a mighty oak tree will.
Does any girl really want to have to endure the embarrassment factor of dealing with a cocktail sausage when they've been expecting a bratwurst? Nobody wants to ask, "Is it in yet?" at the height of passion.
Still shaking your head in protest? Then I ask you this, ladies: think of David Beckham in those underwear ads – it wasn't his baby blues that attracted you to the pictures, was it? Or even his rippling six-pack?
No, no, no. It was that bulging package that left you ogling for hours. Now tell me you'd have been in the slightest bit interested if he'd been snapped with nothing more than a jelly bean-sized protrusion in his tighty whities.
There is a school of thought that claims all male appendages are actually the same size once fully aroused but we all know that isn't true. Come on, surely us girls want the journey to be just as exciting as getting to the destination? Bigger is best and not one of you can deny it.
NO says Nilufer Atik, 38, a journalist from South West London
I lost my cherry to a friend aged 19 and it was over in about three minutes. He was small and I remember asking if we'd started, when in fact we were halfway through.
Boyfriend number two was very well endowed. But that didn't automatically mean we had earth-shattering sex. In fact, our bedroom antics were just a bit… considered, really.
I'd laugh along with my mates as we chatted about what we liked in bed, agreeing 'the bigger, the better'. But secretly I'd wonder just where did these women put their partner's massive appendages?
'He was this big,' my mate would brag, stretching her hands across the table. It just didn't seem possible.
But then, a few boyfriends later, I realised it was. He was a cute bouncer I met in a nightclub. After a couple of dates, he revealed he was a penis puppeteer. For those of you wondering, yes, it's exactly what it sounds like – he had a todger so humongous he made shapes out of it on stage.
He was so big, he looked like one of those naughty African statues naked. Before we first slept together, I downed six shots. I had to call it a day after four dates.
Since then, I'm unashamed to say I've preferred average-sized willies. It's not the size of the boat but the motion of the ocean, and all that.
