#2 method: Safe, 100% pleasure and 99% guarantee
F@ck one week after and one week before girl's period. (risky is to F@ck on 11th and 12th day of menstruation cycle)

#3 method: The Safest
Combine #1 and #2, safest

Now if you have to [Disallowed String for - bad word] on the 11 th and 12 th day, no cheaper choice but to use a condom
