The best advice I can give you is to know what you want out of it. Are you looking for some easy money? Porn is an easy enough way to get it. Are you looking for fame? You'll have to put in the work and really promote yourself. Most studios don't do too much hyping actors. Be prepared to do a lot of appearances and schmoozing getting your name and face out there (which in turn leads to more scenes). Also, think about the studios themselves. Many of the bigger studios have a "look" they go for and are ONLY interested in guys that fit that bill. If that works for you, great. If you like more diversity, then think about the smaller studios. Be clear in what you won't do and be prepared to do it. Think of it as a job, a fun, naked, sweaty job, but a job. being professional is almost as important as being hot/hung/piggy, etc.
