I've had something similar in the past, GP said it's just sebaceous glands, sometimes they fill up more and can look white. Mine were a triangle of three just next to the "v" you mentioned, they come and go but unless you're looking hard you probably won't notice them! Hope that helps
If you are concerned only about the lap dance, it's not HPV - it's too soon for genital warts to develop and they sound too uniform for that.
Herpes timing fits, but it doesn't sound like it. It's not painful, also too uniform. Herpes is blisters, as well, not little bumps.
There's no risk for gonorrhea, chlamydia, HIV, hep B or mycoplasma without penetration.
Have you googled or seen pics of Fordyce Spots or pearly penile papules? Maybe it's one of those and you are just now noticing because you are anxious about the lap dance and inspecting things really, really well and closely.
