I wrote about why I hate it here
I hate the money shot
Blogs linked to the article, and I was suprised by some of the reactions. Firstly, there's a lot of guys who really don't like it. And there are some women who find it sexy. So given that, the article does have a few generalisations in it.
One thing that I really do hate about the money shot is that it's so ubiquitous. So many porn films and photos have it, it gets really boring, to be honest.
I realise you're asking for a male point of view, so I guess this post isn't too relevant LOL
