If you continue having sex after ejaculation while using a condom but the condom doesn't break and there is hardly any semen in the condom what are the chances of pregnancy? Could the semen have seeped out? Is this likely???
The instructions on every packet of condoms I have ever seen (including condoms in countries outside the United States) clearly state that once the man has ejaculated, he needs to withdraw and dispose of the condom promptly. Proper withdrawal means you grip the ring firmly, pull out completely and slide the condom off (by the ring! Obviously you don't just pull it off at the tip 'cause that's messy, and risks rubber-band-like snap-back). Proper disposal means tying off the condom and toss it in the rubbish. Do not flush down the toilet.
The reason you must stop once ejaculation is complete is because the penis loses its erection pretty quickly after orgasm . Once the erection starts to subside, the condom immediately loosens, and you'll risk seepage and slippage -- generally termed as condom failure and improper use. Essentially, if you do not follow the direction to a T, then the condom's effectiveness cannot be guaranteed. So is there a chance of pregnancy ? With an improperly used condom, yes there is.
