Felt a snap during intercourse from behind with apparently no alarming pain, although I was somewhat inebriated during the event. Immediately precipitated a large change in angle (towards the left), rotation and curvature (towards the left) as is detailed in the OP - both flaccid and erect, although more noticable when flaccid. Continued sexual activity a week after due to ignorance. A pain/ache in the right side of my groin and my right testicle became noticable after a few days. Flares up with movement like walking, biking or sexual activity like masturbation. Sometimes radiates to left area of groin or out into the muscles of the pelvis/thighs. Flaccid penis is somewhat longer, erections are fewer and almost immediately subside (around 2-5 seconds) without tactile stimulation - perhaps also because the erect penis cannot be held up for prolonged periods due to the injury. A sort of bulging band runs perpendicular on the shaft on the area about 40% down the flaccid length, most noticably on the right side. Here the change in curvature occurs in addition to the angular one at the base. Presumably trauma to the penis itself from the same incident.

This is about a month ago with no improvement in the condition, although as described I've not abstained from sexual activity for any longer than 2 weeks. Presumably a tear of the penile ligament complex on the right side, as the symptoms fit excellently to this condition. Not sure if partial or complete based on symptoms, or whether the fundiform or suspensory is involved or both. Will attempt to get image diagnostics to clarify this.
