I think you do not fully understand what it means. To be barren means to be sick, it happens only when serious diseases and is not painless. This is a xian jewish distortion and blasphemy against our God. Gods do not create illness in humans, kikes do. If you mean you wish to stay childless and wish some magical contraception, best idea would be to not go spread legs around, and masturbate instead. And to have platonic love if at all with any human and sexual closeness only with Gods. "Birth control" pills your Western doctors usually prescribe you destroy woman's cycle a lot, so better perspective in this case is masturbation & Demon Lovers.
