Yes, your penis is still producing semen even after you ejaculate. There is not guarantee that you "cleared" everything out. However, lets say you did and you waited long enough before you had sex again, you are still having sex without a condom. You will produce semen during sex with her. The "pullout method" really does not work in trying to prevent pregnancy.
thehitman357,
When I said 'safe' I was referring to if I was able to get her pregnant this way.
We are not worry about STDs because we are only with each other and no one else.
Could you please clarify how I can get her pregnant this way?
Thanks
Safe from what? You can get her pregnant this way if she is not on birth control. Additionally, you should be worried about STDs. Besides STDs and getting pregnant, you can have sex multiple times if she is not injured and is ok with it and the same with you.
