Was he fingering the wrong way?

You also have to realize that he may have been with older girls before and things that are more sensitive to you might not have been as sensitive to them so like they both said just give him advice!!

Your best bet here is to let the guy know what feels good and what doesn't, if it was your first time most likely its his first or very close to it meaning that he has no clue what he's doing and any direction you can give him will be greatly appreciated. Make sure when you give advice you do it nicely and suggestively as to what you like and he will be very eager to please.

I agree that it is probably a combination of you being sensitive and his possible inexperience. You should definitely tell him what you feel comfortable with and what technique you would like him to use that makes you feel good.

I remember that when my ex-boyfriend first fingered me, I was not only sensitive because it was my first time, but it felt uncomfortable because he seemed to be doing it wrong. I remember it like he was poking at my urethra hahaha.

Tell him or show him how to do it. Pain is something you don't want to be feeling, if you want him to stop say so. Don't just shrug it off as nothing because you don't want to hurt his feelings. You would want him to tell you if the situation was reversed right?

It was probably a combination of the two. Next time you're in the situation if it's uncomfortable for you let the guy know. Usually, asking him to slow down or be a little more gentle will fix the problem. If he doesn't care about how he's making you feel while you're being intimate, he won't care how he makes you feel outside the bedroom either.
