I do not use a condom with my girlfriend however I did with the other girl that gave me a Blow job... there is a little pain when I touch it but only slightly...feels firm around the edges

I believe it was last Tuesday was my last time we had sex...the next day I noticed a pimple and popped it but the puss came out like kind of firm not fast but slow like out of a tube. and just a drop or two of blood

Brief Answer:
Genital herpes is my first possibility

Detailed Answer:

Thank you. I have reviewed the Images. I can see a single sore (an erosion to be exact) with redness, edema and clean base.
I will keep a first possibility of genital herpes rather than syphilis.
I suggest you to get tested with a PCR for Hsv type 1 & 2 from the sore. This would be confirmatory.
Alternatively you may take a blood test at 2-4 weeks from now so as to detect the presence of antibodies to Hsv.
Genital herpes is an STD can can be transmitted by sexual contact (whether oral or genital) with an infected sexual partner.
Going by the morphology of this sore, syphilis is a less likely possibility. This is more of a herpetic erosion which is superficial as compared to a syphilitic ulcer/ chancre. Nevertheless you must still take an RPR test at 4 weeks and then again at 12 weeks to exculde this possibility with certainty.
Right now I would suggest you to take a PCR for Hsv 1& 2 if that is available.
For the sore you may use a topical antibacterial e.g 2% mupirocin cream, twice daily for a week.
Avoid sexual contact and I suggest that your girlfriend should also test for Hsv type 1 & 2.
