I thought about posting this in /r/sex, but it needs a TRP's perspective, and not get some bad BP advice.

Situation is pretty straight-forward:

Girl is 21, met off Tinder.... first date... so one-night-stand. Doesn't know my full name but I'm sure with effort she could trace me down.

Brought her home last night and had sex... before busting, took condom off and busted in her mouth... but I think some may have dripped from her mouth. Unsure. She claims nothing did, but I'm a paranoid person in nature.

Did a second round on her, but forgot to wash my hands. This is where the concern comes in.

I'm thinking about calling her up and just saying a condom broke, so go get Plan B, I'll pay for it.

Thoughts? Am I just being overly-paranoid?
