Does anyone know that how do a portstar has such a long stamina ? OR anytips on increasing stamina.?

Any suggestions. I dont have pre-mature ejaculation, but prefer to have longer sessions.

I was in the adult film industry for awhile. We are put on a very stringent diet plan, eating lots of nuts and whole grains, and very little red meat. We have to work out at the gym alot, lifting weights, running on treadmills, and swimming all help a little bit and getting better stanima. In addition to that, we also have to take drugs that help us ejaculate more and help us with our stamina. You have to have really good control of yourself to begin with, thats why it is really hard to get into the porn industry if your a man. Performing in front of people and cameras is way different than having sex in the bedroom.
