odds are these are just normal bumps - pearly papules or fordyce spots even. if you are concerned, no more home guessing, be seen for a proper exam.
if you've had unprotected sex, you need to follow up with proper testing. you can test for chlamydia and gonorrhea anytime after 1 week post encounter. syphilis after 6 weeks. herpes, hiv and hepatitis after 3 months.
have you had your gardasil shot series yet?
are you sexually active?
apprently if it does you MAY* have genital warts but if it doest then you very very likely can be sure it is another skin condition..i am hoping just thrush.
