(M4GM) I regressed and now I must build a generic harem to build power

Living a world of absolute power through genetic gifts with unique methods to grow said powers should be cool until you realize that the only way your powers will grow is through sex except the one time I used my powers when I was younger I disfigured myself heavily, now here I am at 16 again somehow not dead and a video game screen with the word "THE HAREM King's RETRY" Which isn't normal but very enticing.
