Hello Derick,
By "grinding" do you mean you were on top rubbing against her pubic area, or that she was on top rubbing against your genitals?
Performance Anxiety might very well be the cause, especially if this is your first time making out or doing so with this girl.
The "grinding" action may be the cause because doing so vigorously can affect the nerves in the root structure of the penis inside the body and cause a person to lose or never get an erection. Changing positions or tactics should fix the problem. As for PE, just becoming comfortable with each other should do the trick.
I understand your concern and embarrassment; however, there is nothing to be upset about. While this can be considered "serious business" no one should take it so serious that you cannot have fun.
A. Erections come and erections go. No big deal unless you fret and fume and make it a big deal. You can relax and try again several minutes later and probably regain an erection just as you'd do if trying for a second or third orgasm in a multiple series.
B. Experiencing a climax is not contingent upon having an erection. Until you are in your fifties or above, or have a medical condition, erections and ejaculations go together. Older men physically fit or not can have ejaculations without erections, and this is why we have the Erectile Dysfunction meds. available.
So, my recommendation is to relax and not be so hard on yourself. Proceed slowly, and if your erection begins to subside, pause the proceedings and return to making out in order to rebuild it.
Lastly, whether nude or not, I would not recommend grinding without wearing a condom. People in their teen years are the most apt to become pregnant. Consider that you are playing a version of Russian Roulette only with a fully loaded "cannon". Any time it fires in the general direction of a girls' vulva the "ammo" can run down and enter the vagina. Birth control is very important and both of your responsibilities. She must be on the pill or using some other form of highly reliable contraceptive, you must always use a condom, and together the two of you should have a third level of protection--using a spermicide. Do not rely upon one or the other of you for your protection. Look out for and protect A#1--you, both of you. Do not for a moment think you can fool Mother Nature by forgetting one, or thinking that you do not need all this protection. There are plenty of cases where Mother Nature has come back to smite a couple!

GOOD FOR YOU, although, please understand that precum can and does contain sperm, so even getting a little of this fluid on her can be a problem. As a guy who has been there done that before, I can tell you that there will come a time or two or more where you know you should stop, but because it feels sooooo gooood, you choose not to. Don't get caught with your pants down having made this choice in the heat and passion of the moment.
I hope this is of help. Got questions?
