Can You Shorten a Long Butt Crack?

From the research I've done, I haven't found any procedure to shorten a butt crack. Mine is fairly long and the crack starts much higher then it should. It's something I've always been self-concious about and want a surgery to shorten it! Is there any way to do that with plastic surgery? Thank you so much! Also, my anus starts about three inches lower then the crack so there is no need for it to be that long!
