Pimple curiosity

So it's been about several months since I had these pimples on my thigh or what it looks like a stain. I am a bit curious since in my head I think or std but nevertheless, I've always used a condom. I just want to know what should be done and what exactly is it. Thanks I would much appreciate it

this is how it looks like 

Ingrown hairs

Ingrown hair huh how can you tell if it's that? Thanks for the reply by the way. But is there a difference with folliculitis?

I agree, ingrown hair or folliclitus, just visit you gp and ask for fucidin cream... it has an antibiotic through it. Some people just clean the area and pop them and clean it out, but that someone I’m not telling you to do. My skin is a nightmare when it comes to body trimming and shaving. Yours might be the same. You might be better using hair removable cream or just a body trimmer that doesn’t cut the hair so short. 

Thanks , but I dont shave that's the thing last time I shaved my thigh was probably 8 or 6 years ago. I am a bit worry if its folliculitis.

I was hoping if someone can atleast help me identify this thanksss
