So about a month ago i noticed 3 really small pinhead sized dots under my frenulum. They feel identical to scabs and they are slightly painful. And now a few days ago I discovered a hole on the underside of my frenulum. Doesn t look infected or anything, but it is slightly alarming to say the least. More of an annoyance than anything else. But it does worry me that it could be symptoms of an std. I would go in for a check up, but i currently lack the money for a co pay.
