Please can you advise what the affect of sterilisation (via either tubal ligation or vasectomy) has on the sexual energies and the practice of alchemy? If one parter is sterilised will the alchemy still work the same for the unsterilised partner?
What other suggestions do you have for the prevention of pregnancy apart from simply withholding the sexual fluids?
Are there laws relating to nature / karma that affect the conception of a child?
Thank you :-)
