You could not have acquired any STD from the exposure you describe. Your symptoms are classical for genitally-focused anxiety. Almost certainly your symptoms persisted or returned after the cipro because you didn't have an infection, i.e. there was nothing for cipro to treat. (Your doc probably prescribed it as a precaution, not because he diagnosed anything.) There is no risk to your regular partner.
Continue to follow up with your doc if your symptoms persist or you remain concerned. But truly, don't worry about this. You don't have an STD.
Good luck-- HHH, MD
If either your or your girlfriend have had sex with anybody else in the last few months--for example, if she is a relatively new partner--then she should be checked for STDs.
She did insert her fingers inside her vagina and inside her anus and then masturbated me (not circumcized). So she did have avginal and anal fluids on her fingers when she touched me.
I understand that the risk of STD transmission (including HIV) in such events is rare but can it be FULLY rulled out? No risk whatsoever?
Won't be bugging you, promised!
