Hi, so my boyfriend and I were fooling around yesterday, and he ejaculated in his boxers, which seeped into his sweatpants. He wiped both articles of clothing thoroughly, but it was still wet. I sat/grinded on the wet spot a few minutes later without underwear on. Can sperm travel through clothing? I have read many conflicting reports about this. Some say it can, and others say it can't. This happened on Day 8 of my cycle (yesterday, April 20th), and my fertile window starts on Day 13 (April 25th). I am predicted to ovulate around Day 17 (April 29th). Also, how long can sperm survive inside the female reproductive system? If any sperm did enter, would it be safe to say that it will not survive until the day of my ovulation?
