I've noticed a lump inside my penis, dorsal side directly behind the glans, rather quickly growing, hard, and has become sensitive to examination, has caused a curvature, and is causing noticeable discomfort during sex.  what could it be?  approximate time from discovery (felt like a thickening of a vein) to thumbnail size (width) 1 inch @ length, and thicker near the glans (@3/4 ")  less than 60 days.
Hi, It can be condyloma accuminate or some mass formation there. It's better to get it removed or to take a small biopsy for histopathology examination. You can provide reports once done. If you have any history of unprotected intercourse than mention it. Hope I have answered your query. Let me know if I can assist you further.
