I really can't say i notice who gives a good load in porn. This may sound strange but i tend to focus on the female actress.....
i know i'm strange
LOL
?!?
Perhaps you missed my point.
For example, see a face like Jessica Jaymes get properly sprayed in her mouth and swallowing is a turn on. Of course you concentrate on the girl, but you're telling me you wouldn't care if she was being pounded by a soft small dick that dribbled on her face, opposed to her enjoy a big dick and getting her face being really sprayed? You can also tell when the actress is being properly fucked and is enjoying it. Call me crazy.
For me a bad ending would be like watching a huge heavyweight fight but right before the knockout the fight stops.
