I am having sex and after sex he gets an irritation on his penis, I also get mild symptoms like burning lower abdomen an skin itching, I had test done an I don't have a vaginal yeast infection or any sti or std and I am confused because this is the second time this happened. The first time we had sex with a condom and two weeks after he said he has been treated for yeast infection but how could this be if we used a condom, the second I was worried an when we did have sex we didn't use a condom and he said his dick started to burn but I still don't understand because I took all the test as possible an I clearly don't have any infection or disease. I clean myself properly and take care of my body but why is this happening, I am feeling ashamed of myself because he makes it seem like something is wrong with me and I don't take care of myself properly.
