Some Old Techniques

As a young teenager I experimented with different ways to masturbate.  Here are a few I tried but rarely ever used once I got older. 

Pillow fucking. I found that the texture of the pillow and pillow case were way too intense for me.  While it did feel good, it just wasn't something I continued doing. 

Mattress fucking, pretty much the same experience as the pillow. 

Vacuum: My parents had an old Rexair which has a water collection canister.  The suction was very powerful and while it did the job I often times had a weird after taste in my mouth. I have tried other vacuum systems but the suction they provide aren't even close and for me isn't worth the time. 

Water Power. Dicovered when I was 13 it provided the best orgasm of my young life.  I also liked the easy and effortless clean up.  But being in my mid 50's today, I'm not as flexible as I used to be and getting in and out of the bathtub can be a chore. Plus, right now I don't have an adjustable shower head in my shower. 

What are some techniques you've stopped using over the years and why?
