Ive had unprotected sex with 2 girls and months after having sex with the second one whom i had tested and didnt have anything. i noticed i started getting red dots on my penis head. every month or so a random dot will appear. the dots are about 1 cm by 1 cm. they are flat dull red and painless. no itching or burning. this most recent one just wont go away ive had it for about 1 and a half months now and it seems to be getting only bigger. they dont nessecarily scab they just kind of get dry and sometimes flake a tiny bit. no white center to them no puss just a red dot. its very annoying. anybody have a clue what it could be?
