Greg is a 24 year old with a lifelong fear of sexual penetration. Ever since he became aware of his own sexuality he has known that he has not wanted to have intercourse. He says that he is heterosexual and that all his fantasies are about women. He can masturbate to these and has had a series of girlfriends - with whom he has been sexually active. He can achieve penetration, but is aware of a general anxiety that sweeps over him. He says that he prefers his girlfriend to masturbate him with her hand, or that they masturbate themselves in from of each other.

He and his partner Joanna want to get married and start a family. Greg wants to deal with his problem. Joanna thinks that Greg is frightened of being intimate with her, and possibly not wanting to make a commitment to marriage. Greg denies thus, and they have both argued a lot about this before coming to see a therapist.
