Okay so the last time I had sex was like 2-3 weeks ago and we used a condom and the guy was so paranoid that he checked the condom to make sure it didn't break. And it didn't! We are completely safe and I am on birth control but my nipples have been seriously sensitive today. I do feel like I'm coming down with a sickness because I have been for about 3 weeks now but does anyone. Ahve any idea why it's happening and how to make them stop being so sensitive
