I made the terrible mistake of unloading my initial porn collection when I got married. In theory, it made sense at the time, but she really wasn't bringing an "A game" to the table (or bed), so I began missing "the girls"..Trinity, Tracey, Renee Summers, Christy Canyon, Lisa Deleuw (sp), Little Oral Annie and Sarah Jane.
I eventually rebuilt the collection...but some stuff I never found again. This forum has been terrific in respect to occassionally finding some of that old stuff.
I had a few great hiding places...like under the insulation in the attic crawl space, but would eventually get too lazy to return the tapes to the hiding place.
Another technique was to label the tapes with titles (or place inside boxes) that she would have absolutely no interest in viewing. I filled all my "Avengers" VHS boxes with porn. (The fact she wasn't interested in Steed, Mrs Peel or Tara King was also an indicator the marriage was doomed
I wouldn't recommend tossing the collection if you get the long face from the doctor...if you recover, you'll just start rebuilding and no sense paying for the same stuff twice.
The most potentially embarrassing stuff I have is when Tracey Adams and Trinity Loren moved on to fetish movies. Whoever goes through my "estate" should realize I followed the actresses, rather than developed interest in the film's content. If they don't follow that logic thread, I'll be too dead to really care.
