Null Bulge

A nickname for the bulge created in the crotch of a person with a penis, while said person has been denied access to their own penis. The word "null" in the name indicates that the ability of that person to make use of their own penis has been "nullified".

A null bulge can be formed in real life by having the person wear a chastity cage and over that some sort of underwear or speedo, smoothing the appearance of the crotch into a bulge.

In a furry art, the null bulge is created by having the character encased in a form of compliant rubber or other tight-fitting material that prevents the character's penis from becoming erect or being touched.

Having a null bulge can be considered a fetish which has some similarity to the desire to be in a chastity cage, to receive sexual pleasure exclusively from anal penetration or generally submit to another person by relinquishing control of their sexuality.

I made sure my boy can never play with himself again - look at his feeble attempts at manipulating his little null bulge!
