Thanks for your question and concern. You are likely to be affected with genital herpes and what you have found from genital herpes pictures might be true, in that sense. The lesions and blisters you found might be due to genital herpes infection caused by Herpes Simplex Virus (HSV type 1). These type of lesions are commonly associated with herpes and not due to other STDs. As you experienced, genital herpes symptoms are usually seen within 7 days from the infection. However, this infection is incurable but you can avail relief medication from your doctor. Hope my answer helps. Take care.
