I discovered anal stimulation way back when anal sex was foreign to everybody except gay men. My first wife would lay me out on a sheet or large towel and start out to give me s "hand job." We both developed this thing about who takes the longest to orgasm. So shorten my orgasm time she would use KY jelly to lube up my genitalia as well as my perineium. When I was as hard as stone, she would insert one, two, three, fingers into my anus. I would have orgasms that felt like I would pass out from them! Well, we got divorced and my next mate enjoyed the same thing, and she wanted to have anal sex performed on her. It was like I hit the sex lottery: deep throat, hand jobs with anal stimulation, and giving anal sex. Her favorite was being "eaten out." I had never experienced an orgasm with a woman since who orgasmed like she did! She would go off for 15-20 minutes. Then I could not resist going down on her again! Well, we broke up: she like doing that stuff with my friends, too. My next two relationships were a bust. Any oral sex was drudgery and duty bound. That is when I began to do anal masturbation with "foreign objects." Years later, however, the advent of superior material for dildos/vibrators initiated a new era in my masturbation habits. I have a couple of toys: one is average, while the other is a monster: 9" X 6.5"! I only use that one if I have lots of time and muscle relaxers! The first time I used it, I almost fell down with pleasure, orgasm, and delight!
