Hello,i want to ask a question,can sperm pass through clothes, my girlfriend and i did dry humping and i ejaculated on her,i was wearing underwear and she was wearing short and underwear,she missed her period?

It is probably impossible the sperms going though all layers of clothes and then gain entry to her vagina for the conception to happen. To erase any doubt, an early morning urine pregnancy test can be done if the period does not come after 5 days of missing.

Sperm die quickly (minutes) when exposed to air drying. The risk of the activity as described is not zero by very close. Some normal women occasionally skip a cycle or two. If this is from pregnancy a simple urine pregnancy test should be positive.

While you are not at risk of pregnancy from this episode, your behavior is putting you at risk of pregnancy and STDS.
