Vaginal Lumps

If you have never even made out without your cloths, then you are not to worry about any STD’s. If you have made out with a guy without your cloths on, you are still susceptible of STD’s because many std’s like herpes, molluscum and HPV are transmittable through skin to skin contact. If this is the case, then you should see a doc and have this checked.
The masses you ran inside your vagina are probably juts normal anatomical masses. Vaginal wall is not a flat area but is actually very bumpy and contains folds. If these cauliflower masses are on the skin surface, you should have them checked anyway.
It is really impossible to say anything without examination.
