Hi doctor.. I have a concern and I'm listing all the pointers herein too .. So me and my boyfriend were dry humping (rubbing our genitals) while standing, he ejaculated and I felt his cum on my upper thigh .. 1. We both had our underwear on 2. I wiped the cum off with water and changed my underwear too 3. I am a virgin 4. My periods are due after 10 days 5. We did this while standing Please tell me is there any chance of pregnancy? Do i need to take pill for safety??
