If i were making out with my girlfriend and i precum and i see the wet spot , can the precum get her pregnant though the clothes , ? thanks

Super Sperm: While I cannot give you a "free pass" as if a sperm DID make it through your clothes, through her clothes, into and up vagina and fallopian tube, then yes, could happen. Oh, and she'd have to be at/near ovulation in cycle. Would call it a very low risk activity. If she should be late, can always check home pregnancy test for reassurance.
