You realize that you had been thinking about this all wrong. It becomes obvious to you that women clearly have the better deal in life, despite what feminists claim. Women get to wear prettier cloths, multiple orgasms, men always do what they say, they almost always win in custody disputes, they get an excuse to yell at people every month, multiple orgasms, sexist people assume that they don't know what they're doing so it's always low expectations, they have the ability to attach themselves to a man and never have to work a day in their life, and multiple orgasms!
You run back to your workshop and spend the next few days building. Your efforts are rewarded with the creation of a Fem-Ray! Its a ray that can make you fem. Without getting too technical, it's a restructured Eisenhower field suspended in a Oliver-Anthony event matrix that uses reconstituted trans particles to alter the space time continuum into mimicking the alternate dimension wherein the subject developed a mutation in their XY chromosome that results in them developing as a girl while maintaining a local stasis effect on the nervous system.
So basically it's a gun, and anything you shoot it with is turned into a girl, and the whole world except for the shooter and the one transforming remembers that they were always a girl. NBD.
You say one last goodbye to your little friend, you raise the gun to your head and pull the trigger.
