the urethral sponge is around sensitive nerve endings, and can be stimulated through the front wall of the vagina. some women have had strong pleasure from stimulation of the urethral sponge, but others have found the feeling to be not good, as irritating. the urethral sponge is around the clitoral nerve, and since the two are so closely inter-connected, stimulation of the clitoris may stimulate the nerve endings of the urethral sponge and vice versa. some women enjoy the rear-entry position of sexual intercourse for this reason, because the penis is often angled slightly downward and can stimulate the front wall of the vagina, and then also the urethral sponge.
