Discovering the G-spot
The famous G-spot, as we saw in the anatomy section, is a sponge, the urethral sponge, and it is actually an area rather than a spot. It's the erectile tissue that you can perceive inside on the upper wall. It's a slightly bumpy tissue, and it will become engorged with arousal. As the woman becomes aroused, the area will become more puffy, and its sensitivity will increase.
During G-spot stimulation, your partner might feel the need to pee. This is because you are stimulating the bladder canal. If she seems uncomfortable, explain to her why she has this feeling and reassure her that even if she relaxes and lets go, no urine will come out. Of course, if she would like to take a bathroom break, this is perfectly acceptable.
As your partner becomes more turned on, the feeling will either go away or change to something stronger.
This is a very sensitive area and should only be touched when the woman is very aroused, otherwise she won't experience pleasure, just discomfort.
