if a female tells you you are the first person she has ever sent nudes to is it a fun fact she is pointing out or does it have any deeper meaning that i cant tell because porn has sort of made me just "ok" when i see a females body

How old is she and how easily did she send the nudes?
It probaly dose'nt mean much if she's willing to send nudes at all. Everyone has a first time. have you been actively sleeping with and dayting this girl for a while? If so that's different, and it could been seen as an extension of your already existing sexual relationship.
