I was recently treated for an std. My boyfriend was also treated. The day after he was treated, 4 days after I was treated, we had sex using a condom which he put on correctly. I’m still experiencing a slight burning sensation when I go to the bathroom. It isn’t bad but it’s uncomfortable. I’ve used two doses of my three night treatment for a yeast infection because I heard the treatment for some stds can give you a yeast infection. Do you think I should get retested? And should he?
