I went to a massage parlor and the asian lady that massaged me sat naked on my back/buttocks and grinded some. I finished with hand-job. I did not have sex or any penetration. 3 weeks later I notice a small red lesion in my skin on my extreme lower back.I have not noticed it there before that I remember. It is flush with my skin, It is reddish/tan.. It is not a bump or papule. It is just in the skin. I am worried that this could be a syphilis chancre forming. It has been like that 5 days. No other symtoms. It seems to be becoming more distinct like 2 more round red places still under the skin. I am worried. any help please,
