I had protected sex almost two weeks ago with someone I do not know too well. Recently I have gotten some small pink bumps on my arms and couple in other places but none on my face or genitals. They itch a little and sting if I put pressure on them.

Is this an early symptom of an STD and if so, what type? There's a chance that this may be from allergies, but I am more inclined to think STDs.

Just go to the doctor and get tested to be sure.

Two weeks ago you say?

Assuming that you haven't been in the night air and been bitten by a couple of mosquitoes, I can only suggest that you might be suffering from the early stages of that dreaded
condition known as Copulatius Absentius.

It only gets worse, the pink bumps turn into red welts, and EVERY boy knows what it is you are suffering from.

Quick cure, go find a willing participant and indulge in as much sex as you can get. the more often, the better. Warning, don't just limit yourself to one partner. Multiple partners are highly recommended, it also increases your popularity at the same time. the pink bumps will be a thing of the past.
Guaranteed!

If you had *protected sex then it may be an allergic reaction to deodorant or clothing. If you start to drip drip down there or it starts to smell a little funky you might need to go see your local clinic. If it starts to itch try not to scratch. ask your MD to check it out.

Could be scabies! check with your local health dept or your physician. Do it for your own health.

Wow, go get checked.

well normally you would have something down there. but you say you don't so that is good. but it sorta sounds like scabies. that is a curable disease. basically it is lil bugs that crawl on your skin. it itches and will be red and bumpy. make a Dr. appointment go get checked. it could be nothing or maybe an allergy to a soap or something. good luck and go make that appointment!!!!

If you are concern, consult your doctor immediately.
