It would depend on what phase your are in on your cycle, If you are in the most fertile part of your cycle then it could be up to 3 to 5 days. This also means that the man needs to be in good condition
Generally, during your fertile time, sperm live about 3 days, and sometimes 5 if they can get into the cervix. Some research also says that if conditions are absolutely perfect, they can live up to 7 days. This is rare. When you are not fertile, they generally only live a few hours since the vagina is normally acidic and sperm need an alkaline environment to survive. Semen, menstrual fluids, and fertile cervical mucus all provide a better environment for the sperm since they are all alkaline fluids.
