pulling out does work, but not well.
if i had to make up a number, prob 90%, and thats not even close to good enough.
but condoms loving suck, i would prefer no love at all to those.
so i got fixed almost 5 years ago.
but there is zero reason a girl should be having love and not on the pill. you better be taking her cherry that day, otherwise shes a dumb piece of stuff for not being on the pill and you should move on.
