There does not appear to be any chance of pregnancy from the little you have said, provided I have understood you correctly. Some clarification would be helpful.
- You can only get pregnant if sperm enters your vagina at a fertile time. You have not mentioned anything about sperm or your period history.
- "his dry hand touched my vagina" - How did that happen if you were wearing jeans? Your vagina (birth canal) would not be readily accessible. Even just touching the entrance to your vagina would be difficult.
- Were you wearing underwear as well as jeans?
3 days ago, my boyfriend accidentally rubbed his penis on my vagina (only for about 1 second). He wasn't leaked or ejaculated. Maybe a little wet. But it was just rubbed. It's not even inside. Can that make me pregnant?
