Hallow Dear, Non-erected penis cannot be inserted into the vagina. Vagina is not an open tunnel. It a closed space having potential of opening to a large extent; and opens as per the object passing in or through it. Hence the penis should be erected hard enough to enter into vagina by exerting a sufficient rigidity. The very fact that your penis could enter into the vagina proves that it was erected. You had this venture without condom. Once the penis is inside the vagina, even though it has been withdrawn before the ejaculation, there is always a risk of depositing pre-ejaculatory secretions (precum) in the vagina. Precum do have some sperms in it sufficient to fertilize the ovum. So every insertional intercourse should be protected by Plan B post coital contraception if it is not protected by any other method. So, now wait for her menses to appear. If she misses her period, it would be wiser on your part to perform pregnancy test on her overnight first morning urine about a week after missed period; earlier the test may report false negative result. Alternatively you may opt for Beta hCG test 10 days after this incidence. If she is pregnant; and if this is unwanted pregnancy, you may choose to terminate her pregnancy by medicines upto 9 weeks of gestation. Else, she may get the pregnancy terminated by surgical method. Please report to a Gynaecologist for either of the method, if she is pregnant. I hope this helps you. Dr. Nishikant Shrotri
