Re: what if you wore a condom the first time then the second time you did the pull ou
Well, pull-out method is never a good idea but it is even worse if you have already ejaculated once (wherever) and then put the penis back into the vagina without urinating and washing it. You didn't actually say if that's what you did but if so, you should probably get her to go take the morning after pill if there's still time (up to 72 hours later) to keep her from getting pregnant (it isn't instant).
If you're talking about two separate instances that happened hours or days apart, then there's less worry, but still some risk. You have to use a condom every time, especially for the reason above.
