Hi, I woke up this morning with a small bruise on my penis, I am concerned that it may be herpes, though not sure what to be looking for. I had sex about two weeks ago with a new partner. I have no pain, itching or burning, the skin is not damaged in any way, other than minor bruising at the base of my penis. The bruising is circular in shape and 1-2 cm in diameter. I did vigorously masterbate last night, I am hoping it is a simple bruise and just scared to death it may be something else. Any thoughts will be very helpful!

Thank You
