Me and my gf engaged in Dry humping without clothes after 5 days from the end of her period. The humping did not involve poking the vagina with the penis. But it was a sliding motion of the penis on vagina. At one moment the penis was wet, not sure if it was her pre-cum on it or mine. On other instances it was my pre-cum but not sure if there was contact of the tip of the penis with the vaginal opening. Is pregnancy likely? She did not take an I-pill. What steps should I take further.
