Unless you are involved in Physiology- Sex -or Medical Research I would highly recommend to forget about the complication and theoretical approach to hot spots on a women's body.EVERY area of the body is stimulable and arousable, as it "builds" the road to orgasm, the final desire of each erotic encounter. Hot spots, i.e. breast nipples or clitoris vary from woman to woman a bit. The openess, the relations ship a woman has with her own body, namely her sexuality, will determine whether she can enjoy and become stimulated being touched in all different areas of her body. A woman could have 100 G-Spots if she is blocked or inhibited in her sexuality it will not help her. What it comes down is the partner you are dealing with, her comfort with her own body, with her woman hood and her sexuality. And then there is you, the one who is worried about performing well, being a good lover. Yourself you just need to go into the situation with YOUR self confidence as a man, as a lover and you will not have to theoretically approach it. Instead you shall approach it with your senses, your intuition, your observation, your erotic lust and your reaction of enjoyment to it!
