Here are the details of what I have:
Lost virginity on the 2nd of October , she has had 2 other partners (she is 15, I am 15 and a half), always used condom, we foolishly didn't. We are currently monogamous.
Sex again on 4th of October, used condom this time
Small red bump 3-4mm diameter, dry, slightly shiny, painless, firm. Appeared on 12th or 13th, slightly forward from base of shaft. Second one appeared about 24hrs after, slightly down from the head, on the underside of shaft, both completely painless. Thought was ingrown hair, squeezed, only small amount of blood came out. Seem to be going away, washing everyday. On 16th, bump on underside of shaft gone except for very small scab from when I squeezed it thinking it was an ingrown hair. I am worried about it maybe being a syphilis chancre.
Should I be worried about it being an STD, or am I being a little too paranoid?
