A week ago my GF and I were messing around (not having sex) and she got some "pre-cum" on her hand and about 3-5 minutes later, she put one finger into her vagina for a matter of...10 seconds...
She's not the type to leave a wet, sticky substance on her hand for very long (she doesn't remember if she wiped it off) and I have read that sperm dies when it dries and that pre-cum contains very little if any sperm.
She shouldn't be starting for another week or so...should we get a test?
She's not scared...but I am...(weird, I know) I just need some peace of mind here...
Thanks!
