I don't view it as being sexual. Too many people wear this corpo slogan as if it's just "proud to be X." It could be sexual, but unless I see other things that go with being overt, fun, sexual, joking, then I can't really make the conclusion.

I'm not saying everyone should think like that, just that plenty of people can see a woman wearing "Italians do it better" and not think sex.

And I'm far from being an ace. No idea why it doesn't sound like sex to me.
