I really would not do that if I were you.  I'm not gay, but I do have friends who are part of this trade.  I am actually pretty good looking myself and once asked what are the chances for an all woman clientele.  They told me the truth, the vast, vast majority of male escort calls are from males.  Women can get laid, no matter how fat and ugly.  If you are good looking however, you probably can get into work stripping and the like.  You might then take a few escorting duties if necessary.  As for starting a business if you should still choose to go forward, it should not be difficult.  You simply need some good photos, submit them to some sites which traffic in this area.  Buy some condoms and make sure your technique is good.  Save up some money for a lawyer too.  Get about $2000 or so.  Shouldn't really need it in the Bay Area.  Most male escorts don't seem scared to show their faces.  If you have a regular job or are thinking of having one, this might be a consideration.  If you have further questions or need legal counsel, contact me at [email protected].  Best of luck.
