how noticable are they at first ( do they start not that noticable and get stronger?)
No they don't… you will usually know after a day or two that you have one( for guys) within the first 3-5 days( for girls). The symptoms will stay with you for several weeks or months depending which STD you have.
Please let me know when you find out. my husband has been "busy" and I am having discomfort. Thank-you!
