Becoming a male adult star is seriously difficult because the competition is massive. Even if you have a good body, are well blessed, and good looking, you still have to 'perform' to order which is far harder (ahem!) than it looks. Can you perform in front of twenty strangers with a girl you don't fancy? Stop and start every few minutes for four or five hours, and then climax to order? If you want to try a simple test, invite five of your male friends round and masturbate in front of them. Can't? Forget it, this is not the career for you. Probably the only way to get in these days is to go with a girl you perform well with, but be preprared for her to get work, and you to be ignored - the industry needs new girls, it never needs new men.
Finally, it messes with your head, makes intimacy very difficult, is a difficult and strange way to make a living, and the first or second time you fail to perform, you are out.
So - does that put you off? It should, it;s meant to! Treat adult performing like hang-gliding, fun to watch, but scary and dangerous to perform, and best left to the professionals.
