What is the point of wanting to "shoot" when boys/men ejaculate?

This seems to be gaining popularity, probably due to porn and maybe more popular with the younger crowd, maybe not wanting to finish in a condom or because they want to pull out.. but it's not pleasurable really for the woman and it might even increase the chances of impregnating her if you aren't using a condom.. and not to mention you could put and eye out with it.. so why is it such a big deal?? I can understand wanting to stop n start over and over to have super strong orgasm, and the shooting resulting from that but just shooting to be shooting?? please enlighten me :) Why the fascination?
