uh yes... its hard to make it feel good. theres no way to "screw up" really. you could cut them, but thats just because of long fingernails or something. Its different sex with every person, some people like it some way, some people like it another. some hard, soft, fast, slow. and the worst of all is that they usually dont tell you. you have to find out yourself. thats half the hard part. the rest is keeping it feeling good because it is easy to go sloppy. its like leaning to walk. its pretty hard until you learn the concept, once youve learned it, then you need to get the routine down.
