Last week on July 3rd I gave my boyfriend oral. He ejaculated in my mouth without warning me which caused a bit to drip down his shaft. I noticed it and touched that tiny bit between my thumb and index finger. However, I got up and rinsed my hand with JUST warm water (no soap) for less than 30 seconds. From there, I grabbed brown paper towel (which is rough, and not soft at all) and dried my hands completely. We waited 3-7 mins doing nothing. He then continued to give me oral. To make it easier for him, I opened my labia majora with both my hands (which were dry by then). But, I did not touch my vagina at all.
Is there any chance of conception if I was ovulating or on my fertility window?
Thank you. Any answer would be greatly appreciated.
