A week and a half ago I was given oral sex by a girl I have known for a little while.It was unprotected and I ejaculated in her mouth a bit.I know she is sexually active with others.I noticed no visible sores on or around her mouth.However, for the last few days I have been experiencing a slight discomfort toward the tip and feels like mostly inside of my penis.It seems to come and go in intensity which is not unbearable but nagging.I have not noticed any discharge or burning during urination or ejaculation.What could be wrong?Should I be worried because I have never had this before or am I just anxious because I am married and worried to death that it is something bad!!! HELP!!!
