It's really hard to say since you have been squeezing and messing with it, and we don't know how it would look naturally. Things like this normally get bigger the more you mess with it - ever popped a pimple? It looks a lot angrier after you pop it, what with the scab and all.
If the doctor did a PCR swab on it, it wouldn't matter if it was dry. If it's not herpes, and something like a fungal infection or some sort of bacteria, the swab make pick up on it.
The chances of getting herpes from a one-minute oral encounter are slim, even if you hadn't used any kind of protection. If you were to get herpes from oral sex, it would be genital herpes type 1, not type 2, as the number indicates the strain of the virus, not the location.
Have you ever had a cold sore? If you already have oral hsv1, you can't get hsv1 again in a different location. You can have hsv1 already and not know it, since 90% of those with hsv1 will never get any symptoms, and about half the adult population already has it.
The only thing you can do now is wait, and stop messing with it. Let it heal. Listen, your penis is your friend. Treat it kindly. Well, really, your skin is your friend. Don't squeeze and pop and mess with things on it. That's a great way to get bacteria into sores, and to create scarring.
When do your results come back? If you get another sore, don't touch it, and let a doctor see it, preferably one who knows what herpes is.
Don't panic - this could be really anything.
