I have an interesting enquiry to make. My Girlfriend is fasting and is aiming for 10 days. And has made a few attempts but comes into the issue of sexual frustration and increased sex drive that is insatiably unstoppable. No amounts of masturbation will ease the torment. The power and will to resist the urge to masturbate is very tough and she has given in over the past few attempts and has had to break the fast within the first 3-4 days due to this issue. Any ideas as to why this increase of sexual sensation in her genitals and any possible preventative measures she can take?? As of writing this, She is at 40 hours of fasting.
