Pull out method?

Please don’t lecture me. I know it’s not a good preventative measure and I’m not asking if something COULD happen. I know that pregnancy is definitely a possibility. Just wondering if anyone else here actually got pregnant using the pull out method? Is it less effective if you have multiple sessions in a row but pull out each time to finish?

Boyfriend and I got a little carried away yesterday. We had been drinking a bit and didn’t think it through all the way. This may be TMI but we had sex, he pulled out, wiped his penis off and we had sex again then he pulled out to finish, wiped it off and we had sex for a 3rd time and he pulled out. Getting Plan B in the morning but just wondering if anyone actually got pregnant when using pull out on multiple sessions?
