Me and my partner were together. He had his boxers on but I was naked in bed. He was on top of me. I just felt his penis inside my vagina for a few seconds with his boxers on but he did not ejaculate. But there was a drop or two of pre ejaculate on his penis. My period got over just 3 days ago. There was no ejaculation and we didn't have sexual intercourse I could just feel it for a second. Is there any reason to be worried for pregnancy? I trust this site way too much and I thank you guys for being so accurate and supportive.
