According to Osho, a sex strike backfires: sex is a need for women too, so the strike punishes both, turns love into struggle, makes the world joyless, and can harden into a life-draining habit. With contraception available, pregnancy can be avoided; then sex is harmless playfulness between consenting friends—no strike, no guilt, just nonserious, mutual fun.
Don’t punish yourself with a sex strike; use birth control and enjoy sex kindly and playfully without fear.
