Sir, I had unprotected sex with my female partner on 06.09.2015 (5 pm). But i used the pull out method by pulling my penis from the vagina and ejaculated outside. I wiped all the stuffs from my penis then after 10 mintues again had sex with her and repeated the same pull out method. For your information, it was my first ever sex relation with my partner. Now i am much worried, will it lead to any problem like pregnancy as little semen might be sticked into the vagina. So should she take i-pill or not and if yes then will it work on 10.09.2015 ( 4th day of sex). Sir please help me.
