Starving and masturbation...as a form of birth control? Doesn't sound like a good plan to me....Go ahead and eat and play with yourself...and buy condoms to stay safe.
No... the chances of getting pregnant are still very high if you have unprotected sex. What you asked won't make a difference. :)
Oh, either way, no, that won't play a part in it at all. She could still get pregnant if you aren't using protection.
im sorry, i meant lack of food.
