All possible sti/std that cause new painless fluid filled genital bumps every week..? if i leave them alone, they don't quit growing in size. if popped, turns into a scab or open wound that still doesn't cause discomfort. any/all possibilities?

Not an STD: No STD is a likely explanation. You probably know that some features suggest herpes, but herpes never recurs more often than once a month; lack of pain, redness, etc also are against it. Beyond that, I have difficulty judging the cause. Presumably you have seen a doctor, right? If you haven't been to a dermatologist, that should be your next step. Ask your doctor for a referral. Good luck!
