My boyfriend and I were having sex with a condom and he ejaculated a small amount. We proceeded to have sex and when I put on another condom only the top part I realized it was on backwards and it touched the tip of his penis, I reversed it and we kept on going. He wiped the condom with his fingers to clear any sperm. However we are kind of worried now. As I am due to ovulate within two days. Should I be worried?
