hello, so the other day i noticed a small pink spot in my pubic area, no there are are atlas 4-5 more pink blotches. they do not appear raised and they have not changed much over the course of 2-5 days. no itching, burning in the area. i had protected intercourse with a CSW about 4 weeks ago and I'm afraid this might be some std. the marks are very small and very light pink spread throughout the pubic hair area. can someone tell me what this might be?
