Hi. I'm 19 years old and have a girlfriend of 2 years. Within the last 2 days i've noticed some small flesh-colored or slightly ligher than flesh-colored bumps on the underside of my penis and around the shaft and one or two on my testicles. There are one or two above the shaft and where my pubic hair would be. A majority of them have a hair growing out of them, either through the center or the side. I'm not sure whether they've been there longer than 2 or 3 days because I just shaved down there, but i'm relatively sure they must have been. There is no itching or pain or redness, but i'm extremely worried about this.
Background info: girlfriend was a virgin until me. Have not had sex with anyone besides her in 2 years. Had sex before that with a condom.
Please, any help you can give would be greatly appreciated. I've seen other topics similar to this, but I am freaked out enough that I need as much confirmation as possible that this isn't something serious.
Thanks again.
Edit: the night before I noticed them my girlfriend and I had sex for an extended period of time with alot of "mess," if you know what I mean. I didn't wash off after that, as disgusting as it may sound. The areas that the bumps are in are generally the "dark" spots where my penis would rest on my testicles and where alot of rubbing occured. Could this be a possible cause?
