Hand Practice is not harmful as u think. It will control your blood pressure. So you must do atleast 1 time in a week. If your wife or girl friend does not want to vaginal sex then you can say her to hand practise. She will enjoy it. If she doesnot intersted in sex, then say her to hand practise with your penis, then she will be excited to sex and your sexual hunger will fulfil.
