I am a 16 year old virgin. 3 weeks ago I shaved my genital area for the first time. I got the usuall small red bumps everyone says you get. But there is one on the bottom shaft of my penis and it is bigger than a zit. It is red only, doesn't hurt, is there all the time, and nothing has secreted from it besides when I squeeze it, but even then it remains unchanged.

Don't squeeze it. That will just spread the infection. It could be an ingrown hair just based on the circumstances that you've recently shaved. Ingrown hairs can lead to really bad infections and you would want a doctor to remove it.

Go and see a doctor to know for sure.
