Trauma: You may have traumatized the shaft of your penis because of your girlfriends tight virginal vagina and your rapid removal. Have no fear. Your penis will heal in a few days. A word of earning however, you are playing with fire when you have sex without a condom.

Likely ingrown hair: Most likely it is an ingrown hair possibly getting infected. You can apply a topical abx like neosporin. If not improving get it checked out by your doctor. Does not sound like an STD though.

About two months ago I pulled a hair from penis shaft and now a red bump has formed, it doesn't hurt but is very visible. How can I treat it?

About two months ago I pulled a hair from penis shaft and now a red bump has formed, it doesn't hurt but is very visible. How can I treat it?

May just wait...: The red bump may be still the healing scarring effect after pulling that hair out, which could be related with its corresponding sebaceous gland. If not hurting and not changing in its size, may just watch and see. Of course, it is hard to give right diagnosis for right care without a direct look at & feel on it. If still in doubt, seek evaluation and counseling timely as needed.

What to do if I have painful, red, hard, bump on shaft of penis?

Penis bumps: Penis bumps can be many things. Some STDs, some not. Only general advice can be given without a photo or physical exam. Top 2 photos are non-STDs: Fordyce spots (sebum which can be extricated by M.D. or left alone), Infected hair follicle (plucked and kept clean). Bottom 2 photos are STDs (HPV and Molluscum) to be evaluated by your MD so s/he can rule out other STDs and council you for prevention.

I have a tiny (~1mm) bump on my penis shaft ~1/4 of the way up. I'm uncircumsized no sex for about 2 yrs. No itch pain or redness. Could it be cancer?

Penile cancer is: Rare, especially at your age. It will usually be demonstratted underneath the foreskin at the glans of the penis; I can say with confidence it is not cancer. There are other things it could be but that is very low probability.

First: First of all before answering your question, I need to emphasize the importance of using condoms every time you have a sexual encounter (genital, oral, and anal) with anyone. You must protect yourself from std's which can be very dangerous and harmful to your health. Now back to your question, you could be dealing with a sore secondary to a syphilis infection, or less likely warts, or herpes. It's very difficult to say with the information you gave and without seeing it. You are also at a high risk for gonorrhea and chlamydia. If its not an std it could be a pimple or a small abscess. Regardless you need to be seen by a doctor right away. Your local health department should be able to give you a list of clinics that screen for std's. You can be anonymous if you need to, and they are usually free. Please have this checked out as soon as possible.

Needs Exam: Without seeing the bump, it could be anything from an actual pimple or infected hair follicle to herpes infection, early syphilis sore (doubtful), irritation, etc. See your doctor.

Papules: The little bumps on your scrotum are normal actually. They are glandular/papular in nature. When they occur on the penis their called pearly penis papules. Don't go squeezing them. Your likely just invite infection. Now the rash, it could be anything from fungus to heat rash to an STD like syphilis. You should be checked by your primary doctor.
