Country boy goes to the city, encounters genetically modified "pork-upine" prostitutes and shooting galleries with live targets

I'm pretty sure this was in an anthology of older stories that I read in a paperback in the 90s, although the book may have dated from when my parents were growing up in the 60s and the 70s. The protagonist is a country boy who goes into town. There a sort of a Coney Island setup with booths and items for sale. I remember there were prostitutes named something like "pork-upines" with vaginal openings scattered all over their bodies as well as a shooting gallery where you practiced on live targets, although I'm not entirely certain if they were robots of some sort, or genetically modified. The protagonist is horrified at the excesses of the city, but samples the wares of one of the prostitutes, falls in love with her, and buys her freedom.

I know it's a very vague description, but I'm hoping those salient points strike a memory in someone. It was in English. I read it while in the United States somewhere in the 90s, and I'm pretty sure it was one one story in an older paperback, the sort with the cheap paper that browns with age. It's also possible that it's one of the shooting gallery targets he purchases, although I'm pretty sure it was one of the prostitutes.
