Sure but if you go there you don't want to just leave without ever having porked one. That's how it is tho. There's probably a Japanese word approximating mudshark for women who accept gai-dick.
Best thing about the place (depending...), if you're male you are The Man. What you say is what it is. Walk in as a couple and they bow to You. Questions are addressed to You. The one without the penis is a very distant second. People think of Japan as the most advanced asian country, which it is, but it's still asia. I'm sure it comes with responsibilities too, like having your shit together at all times, but if you're from the west it's hard not to notice. And your liberated free thinking western woman will notice too and not like her new backseat position, lol.
