Anyone with experience in the industry?

i can understand why it may be a very challenging career - risks of disease, risks of never becoming successful, being frowned upon in society (who cares right). I made one call to LA the guy was asking for pictures of my wee wee next to a object and that i'll probably have to go in raw and probably won't make much at first if ever. Then its hot lights, strangers with cameras, may not be a woman i necessarily am attracted to, come on cue, and must be a certain size. Any tricks people know the stars use like what types of pills or lubricants for enhancement and prolonging the ? Anyone ever get into this not knowing if they would be able to pull it off, how did it go? Please only responses from people that experienced this i don't need judgment calls from mortals no better or worse than me.
