My GF and I had a long slow sex session on Sunday at 3pm or so. We are using the ovulation calander method and "pulling out" to be on the safe side. I admittedly got close to ejaculating to the point I may have(I stopped and slowly pulled out). It was a very safe day on the calendar. She just informed me today that on Monday around 10am she noticed a discharge that she is pretty convinced is "me" not her. I don't know if it is just pre-ejaculatory fluid or perhaps some semen. I did notice her mucus changing noticably after having sex for awhile and I'm wondering if what she is noticing is actually just a different kind of female mucus discharge from the slow/long sex session. She is concerned even though I'm sure she can't get pregnant. Any info would help.
