(Sorry for bad english) Can my gf get pregnant if we were only rubbing? Details: The there day we were hanging out. First we had oral sex (for her) and then he did a little petting session. I always had my underwear on(boxers) and she did not have anything. I just rubbed part of my penis (i guess it was the base not the glans)since I realized that it was risky. i also need to say that I never eyaculated, there were only some wet spots of preseminal in my underwear. Also I did urinate several times before that encounter. Last but not least, she has irregular periods of 28 to 31 days. The day we did that was suposed to be on her 27 day. Now its 31 days since last period. Im afraid she is pregnant, please help
