Most of them are probably drugged up so that must help. Also, has anyone else noticed that for pornstars their flaccid size is almost the same as their erect size? I for one know my erect size is considerably larger than flaccid
Just because you can hold your load does not mean you can't get a boner when a girl is sucking your dick or something
Coz they are not professionals. Man, you're watching the wrong movies. You gotta watch the ones where the 'pornstars' are actually having fun. I was watching this japanese porn, and the main guy came too soon. The girl was like, what the fuck? So the camera man gets undress and finish the girl off. That was so funny...
Probably a mixture of drugs, doing it all the time, and having to fuck girls they're really not attracted to.
The main reason is that they are so used to fucking hot girls that they really don't give a fuck anymore, fluff chicks and injections of adrenaline into the penis also help with keeping it.
In mainstream porn they inject stimulant into the penis to get it as erect as possible and keep it there. It as you would assume gives somewhat of a numbing effect that gives them the ability to continue humping regardless of how hot the girl is, or the size of the anal warts she has.
I believe most diseases are shared inside the business. I watched a scary video about porn about a year ago that explained many of the things you see regularly in porn and what they actually are, eg. fungus, warts, ect.
