My wife doesn't have sex with me except when we're trying to get pregnant. On the other hand, I have such a strong libido that I'm not satisfied unless I ejaculate every day. Even my obstetrician-gynecologist gets angry at me for having a low sperm count and telling me not to abstain a little. I've tried my best to abstain from sex, but... every weekend, my wife's sister comes over to our house and squeezes out all the sperm I've saved up...
