Zag,
Adults have pubic hair.Children do not. I think hair should stay - but can be modified for cosmetic reasons.
Having sex with a guy with hair bristle is right up with body odor as being bad. It takes long enough for a guy to keep his beard shaved before sex - if he had to shave everywhere it would just take too damn long.
Right now my partner has to shave right before we have sex and sometimes again before we are done.
Unshaved pubic hair is soft. Or it can be made soft by use of hair conditioners. Bristle is bristle and has to be shaved. I don't want to wait that long!
