Hey, the chance is very low pero hindi zero talaga, best case scenario, wiping your hand on something before touching her helps reduce the risk, but sperm can survive for a bit so there's still a small possibility lalo na if she's in her fertile window. Honestly, if you're both worried, better to grab a pregnancy test after a couple of weeks or talk to a doctor para sure, but don't stress too much, a lot of couples I know have had similar situations and it didn't result in pregnancy, so you're likely okay!
