My boyfriend rubbed his penis on my vagina. i dont know if any precum came out but he did not cum on it. i am also a virgin so his penis did not enter in my vagina. i am 6 days past ovulation. should i take a plan b?

Plan B isn't necessary. Even full ejaculation at the vaginal opening is low risk for pregnancy (although not zero). Look at it this way: Normal sperm count is 15 million to 200 million per ml. Men with counts below a million almost never can successfully conceive, even with ejaculation in the vagina. The very few sperm involved in touching like this don't have a chance at the egg. Don't worry!

In this situation chances of pregnancy are near 0 as precum as no sperms and sperms have to enter inside the vagina to cause pregnancy. But if worried do a pregnancy test
