So I have been having sex with the same partner for 4 yrs. Now. But we are off and on. But for the past year, we have been doing good.so to the point. About two times in the past 6 or 7 months. I had these tiny paper cuts on my vagina after sex. Wasn't sure what that is or was but we both had it happen at differbet times. Then recently when he is giving me oral sex, my clit will have a itchy sensation that lasts a couple minutes and goes away. That has happened twice already. When we gave sex it also feels like uncomfortable, like he is hitting something that can be painful. My question is, does any of this sound like std related ? I also have had 3, periods and spotting. Which is abnormal BC I have the implant birth control. And had not had a period in over a year..
