Unresolved sexual dysfunctions, between fear and performance anxiety

Luca, invented name, is thirty years old. He married passive fidelity. He never cheated on or left his girlfriend, despite being terribly unhappy, because the sex terrifies him. He has always been afraid of sexuality hit and run and holed up in a lukewarm and gray relationship to avoid facing his sexual fears, his limp erection and his already diagnosed erectile deficit.
