It's totally personal preference of course, but I prefer a natural or just partially trimmed bush...(love the asians!)
As a guy who grew up in the 70's, the clean shaven "y" reminded me of the bad old days when the censors used to airbrush out the pubic hair from nude pictures.
When the trend to shaved pussies started in porn 20 years ago, it seemed less erotic, even though it was once considered kinky. Now it's totally mainstream, and very practical.
Also, IMHO, the natural bush looks less 'professional' and makes a woman look more civilian.
But I say if you can't beat 'em, join 'em, and I have to admit that I partake in thorough manscaping myself.
