This gives great orgasms. Often I'm not quite sure how many I've had! My shower is such that I can adjust the temperature and pressure independantly. In the bath I like to lie and relax for a while before turning the shower on my clit with a low pressure, bringing it closer and making the water rush faster.
Very different sensations can be gained from different angles, distances and movements of the head. I love bringing it right up close to my throbbing clit, hot and fast and humping it-the ridges on the shower head feel great against my lips. Changing from hot to cold and visa versa feels amazing too.
