You just have to mix it up...I can like the looks of a chick all day but if she doesn't do the kind of porn I'm into I won't develop much of an interest in her.
I like hard core pics but sometimes I just want to look at the beauty of a chick doing some solo posing.
I think you posted some b/w pics here a couple of days ago and they were scorching from an artistic standpoint but if all you did was that, I personally would lose interest.
Again, I just think you have to do a variety of things, bring the same energy and enthusiasm to all of it and your fans will like you almost more than what you're doing IMO.:2 cents:
