Sex in need condom is ok?

i don't use any proper methods of contraception - the guy just pulls out formerly ejaculation..it's the same guy and have been for over a year. he's the merely one. i'm STI free so ok there. Him too. so lone risk (i think) is pregnancy. but is that likely, really? cos isn't it simply about 4 days out your cycle when you can bring pregnant (ovulation),...and if he pulls out...is ok, no? what's the chances? You're rolling the dice. You will crap out soon.
NO not ok!
Are predisposed to bet your life that he is steadfast? Because you have already...
It will evolve, you will get pregnant. Just because it have not happened all the same. It is called pre-c um, which the guy can not be exact going on for that part when pulling out. And yes, that too can find you pregnant.
