There's a lot of differnt ways but first it's important to know the age of the girlfriend you're trying to convert...meaning is she a teenager still living with her parents.. or is she's married or single... Not trying to say I'm a professional about it but I can honestly say that I have helped a number of different girls into the lifestyle... but like I just mentioned, I've got to know more about them... and in your case, why do you think she has a hangup about dating or having sex with a black guy... there's got to be some reason and if you can focus on her negatvity, keep trying to work on a more positive actions...
