Just an additional note:
If you have used a condom for ALL direct genital contact and it did not rip, tear, break or slip off, you can rest assured that it was 100% effective in that instance.
Too, if you "always do this to yourself," it might be time to consider using an additional method of birth control with your condoms OR waiting until you're not so stressed and anxiety-ridden about possible consequences to have sex, pregnancy and infection/disease transmission is always a possibility, so there are times in our lives when we're just not up to dealing with all of that. This might be one of them, eh?
