the wife was on the pill before we were married, and we never used condoms until after our 2nd child was born. so we went from 1976, (married in 78), to 1987 without using condoms. she always used the pill up til then, except when we were trying to have kids. and we never had problem with fertilization. the first month off the pill, I got her pregnant. this was the case with the first 2 boys. I remember the first attempt at son #1. we wanted a boy first, and we read some stuff about the Jewish book Talmud, and used some of that info. she finished her period and then we waited for about 2 weeks for the peak of ovulation. I did not have any sex of any kind during this time. my balls were hanging and full when we had sex, and I blew a big load. in feb 88, we had a "sex olympics" nite, and I split a couple Magnums, 3rd son got his start that night.
