Started in 1977 and within weeks was making $200 a week, sounds small now $1,000 a year in the 70s was a good wage.
It grew very fast, as I was in debt for $60,000 I kept the day job. By doing the porn in the evening and at weekends. The day job was growing well also, selling office furniture
1988 went full time and was till I retired in 2009.
