I have had only one partner (my husband) until a couple of nights ago. I was with him once, I received oral, and we had sex. We used a condom and he pulled out when he came. He has been with many girls, but said he is clean and was tested a month ago. Now, I am feeling so much regret and worry. What are my chances that something could have been contracted? Should I go get tested or am I over reacting? All of this is new to me. Thanks.
