Hi Doctor, i had oral sex with a masseuse, she gave me a blow job without a condom. She said she is clean and she is not a sex worker. Thou i think she could be giving blow job to other clients as well. Now the problem is after a month of that instance i feel a little pain on the tip of my penis. The opening is little pink and i was uncomfortable about it because of the unusual sensation. There is no pain in urine or anything. Thou it just happened today so i was worried about it. Also i used a soap daybefore yesterday, just clean the area while taking the shower. Now i dont know if its because of a possible STD or because of the soap but i am really worried. Please suggest what should i do? V.R.D
