this popped up on the middle of the day on friday and the last time I had sex was a month ago and it only burns when I pee but the weird thing is that it has no fluids other than a little blood but can someone tell me if this looks like herpes

looks like syphilis

That does look an awful lot like Syphilis. Get yourself some blood work done, Syph is treatable but the earlier the better.

do you know what are some differences between herpes and syphilis look wise

Herpes are usually a collection of much smaller spots that burst open and produce a pus - here is a description from a medical source:
.
You may feel itchy or tingly around your genitals. This is usually followed by painful, small blisters that pop and leave sores that ooze or bleed. Most people notice symptoms within a few weeks after they catch the virus from someone else. The first time it happens, you may also have a fever, headache, or other flu-like feelings.
