I religiously take my birth control pills, some nights am 30mins-1 hour late (this doesn't effect anything on the combo pill) and I never miss a night. I switched pills about 5 months ago and haven't missed one, and haven't missed one 4 months before that too. My boyfriend also pulls out and we've had only a scarce scarce fewincidents  with pulling out .5 seconds too late (though nothing really even gets in)
