Before I answer your question I would like to get some more information:
Can you tell me if the lady had any visible marks or lesions on her face ?
Only if she did have active blisters of herpes or warts present on her lips or tongue , then she can transmit the virus onto your nipple.
If she had active blisters or erosions she would have been in pain ( if it were herpes simplex)
It would be difficult to comment on warts as tiny warts are painless and difficult to see ( same like molluscum ) and hence whether she had them or not would be difficult to comment. But to reassure you did she have any visible lesions on her lips or around the mouth ?
If you fingers come in contact with inner genital area there is nothing to worry as no STD can spread through that manner .
