Hello sir or Ma'am we are in live in relationship. And early to get married. My partner is totally healthy. We want sex without condom because here is less pleasure with condom. So we want to know safe period for my sex in menstrual cycle. My partner's? last periods start on 11 aug. So we want safe period for sex. And please tell there are how many risk in safe period. And why? Because ova is alive 2 or 3 days. So if we perform unsafe sex on 25th day of m.c. Then why risk occurs here.
