Hi I am a 33 year old male, who rarely has problems when having sex. Lately I haven't been able to maintain an erection. I also noticed that a few days prior to this situation my penis started to bruise. immediatly aftewr the purpleness of the bruising was gone, that day my penis did not get erect at all. ive since been able to get a erection but cannot sustain it. is there a connection between the bruising and the erection problems????? Also i do have a unusual lump on the left side of my pelvic line but it is not painful and i wouldn't notice it otherwise being visible. Could that be a swollen lympnoid?
