Pre-Porn 

Videos, pictures, or anything else watched before more intensive porn, then most often followed by ejaculation. Pre-Porn material does not have to qualify as actual pornographic material.

I'm watching the show friends for Pre-Porn lol.

Anyone down for some Pre-Porn?

Not really in the mood to beat off but I'm bored... Pre-Porn time.

Pre-Porn 

Pre-Porn is an essential ingredient for a nice long jerking session. This is what you view before jacking or jilling off, in order to prepare yourself for your masturbation session, and can include things like: work-out videos, underwear models, and various slightly sexual gifs.

"how long do you masturbate?"

"oh, about an hour or so."
"really? for an hour?"
"yeah, but a fair amount of that time I'm just watching pre-porn."
