I've seen that's it's possible, but HOW possible ????  I can't find any percentages of the likelihood of this.  I'm 5 days late for my period, and I had no penetration sex this month.  My boyfriend has ate me out and fingered me, and I've jacked him off/have a blowjob.  I'm seriously having serious anxiety right now.  I'm taking a test today, but I don't understand.  Wouldn't the sperm have to travel far if it even did get on the outside of the vagina ?? I'd like some statistics.
