Do Kegel exercises necessitate ghusl if semen is discharged? Do the maniyy, madhiy, and wadiy of a woman exit from a single opening, whether it be the birth canal or the urinary opening? And does holding urine and experiencing pleasure necessitate ghusl due to the discharge of semen?

Exercise does not necessitate ghusl (definition) unless semen is discharged. Continuing exercise until semen is discharged is considered forbidden masturbation. Semen exits from the outlet of the child, and pre-seminal fluid (madhiy) and semen (maniy) share the same exit, while post-urination fluid (wadiy) exits from the urinary opening. One should not hold back urine due to the harm involved. A mere sensation of pleasure does not necessitate ghusl unless semen is discharged.
