You think it was different in the past? While there have been exceptions, the only difference in the past it was hard to get caught “with your pants down”. Indeed, now with DNA testing we can uncover all sorts of things in history (none of which we would be allowed, for good reason, to discuss here).
And yes, frum Yidden are different. We were, and will always will be. It even shows up in scientfic research (e.g., a major factor in determining that one form of cancer was sexually transmitted was the discovery that the disease was very rare in our community). But again, that’s not a hidush either.
