do i have herpes?

Hi im 18 and i had unprotected sex a few times with different  partners all 18 years old and all claim they have been tested i had a white head looking pimple right at the base of my penis i popped it and  nothing came out and for a couple weeks it turned into kind of a red popped up lookin thing and it hurt to touch not terrible but it was sensitive it was red but then i went surfing and i dont know if this matters but the cold water turned it to a black lookin color and and the end of the 2 weeks it scabed up but very lightly not like a normal scab on any other part of your body and now there is a pinkish scar left there i was curious cause im enlisted in the military waiting to leave for boot camp and i am rly stressed it might be herpes... im not sure if i describe it well enough but any response would help. thanks

odds are this isn't herpes going on. best you can do is be seen and get a proper exam done.

since you've had unprotected sex, cover your bases properly with full std testing. you can get tested for gonorrhea , chlamydia and ngu anytime after 1 week post encounter. syphilis after 6 weeks. herpes, hepatitis and hiv after 3 months.
