Fred was in a heterosexual relationship before he gave himself over to his base desires.
I have seen this happen to a friend in another city (ran into him through a common friend years after last seeing him). He was no longer in the lengthy “live-in” relationship with his girlfriend. Had lost a lot of weight, adopted more swishy mannerisms than he had in the past, and does not seem to be looking for a steady relationship. Drug use continues to be a factor in his life.
It’s a very unhealthy lifestyle.
Freddie, as with many cases, was molested as a teenager.
