I think the best person to ask would be a man who was circumsized as an adult who had the opportunity to experience sex under both circumstances.
William Shatner was Kirkumcised.
That would be me, I was born into an Irish Catholic family and was not cut but got it done when I was 37, as regards the sex - no difference at all. It's all baloney what they say and I was perfectly capable of keeping it clean before as I am now.
It's all a matter of taste folks, ignore the propaganda, it makes no difference one way or the other.
