I wouldn't say it's more pleasureable but more perverted and hot. In my experiences, girl voices are super cute so it's sometimes hard to finish because you just want to cuddle and hug them. Doesn't help that most of them are into getting beaten up and all that, it's not easy to bring yourself to slap a little cat. 
While with men you know they have been beaten up multiple times in their life so a virtual sucker punch wouldn't bother them and you can be as rough as you want.
