Aaaaannnnd this will devolve into another “discussion” about the “merits” of the rhythm method and how condoms interfere with the natural order.
Well, since YOU brought it up-- NOBODY has advocated the "rhythm method" since at least the late 1970's. You may be confusing it with Natural Family Planning, which has been proven to have an effectiveness rate of 99%. More info here:

As for "condoms interfer[ing] with the natural order," that's a little hard to deny unless you have a condom growing out of your body.
