I experimented with auto-fillatio in my mid to late 20s. I was able to accomplish it several times by laying on my back on the floor, bringing my legs up over my head, and placing my feet under a heavy piece of furniture so I could use my legs for added leverage. I suppose it helped that I was tall, thin, and fairly flexible at that time.
I tried to do this when I was younger. I never made it though. I have a long penis and I was tall and lanky but I never was able to get my penis in my mouth. I did masturbate into my mouth and a younger age though.
