Last week me and my partner got intimated. There was no penetration and ejaculation involved. I was wearing my underwear and full pants throughout the process. He was also wearing his boxer. So there was 3 layers. He touched his penis Through his boxer over my 2 layered covered vagina. There was three layers of clothes when penis touched. Then after sometime he washed his hand with soap and fingered me. Is there any chance of pregnancy?
