me and my bf had sex in 69 position ,i had given him bl**job,h**djob bt he didi not penetrate his penis into my vagina even once also ... i am still a virgin ... he rubbed his penis on my buttocks and ejaculated there and he wiped off liquid with a cloth but i used the same cloth to clean my vagina .. is there any chance of pregnancy ? I got scared and used IDOZ 72 emergency contraceptive within 24 hours .. are there any chances even after EC .. if yes then what to do ?
