In the lab, sperm can pass through screens. It would surprise me if it can pass through denim, however.
You are worried about an event that happened seven MONTHS ago? You did say months. Was that a typo? If that is the last time you possibly got exposed to semen, even if you have not had a period in all the intervening time, you would have plenty of other evidence if you were pregnant now. Such as, a jutting out stomach, and many months worth of positive pregnancy tests.
No sperm can't travel thru clothes
Can sperm pass through cloths??
I think thats impossible. You can get pregnant from pre *** but it has to be released inside of you. I think you stressing is going to mess up your periods because stress will do that. I'm no doctor but I'm almost positive you aren't pregnant..atleast not from this experience. If yall had sex and there was penetrating it would be different
