if you are straight, a biochemical reaction occurs when a hot chick touches your inner thigh, and you are aroused. That doesn't happen when a guy touches the same area. you can't "learn" that.
What an absolutel load of BS. The skin has no idea what is touching it, everything is interpereted by the brain. eg, If you were walking barefoot in pitch black woods at stepped in big pile of bear poo but you couldnt see what you were standing in and couldnt use your other senses to determine what it was you were standing in. The brain could only guess as to what it was standing in based on texture, density etc of the material been stood in. The brain is what triggers arousal, if arousal was caused by touch alone, men would never have to rape women.
