For me it is usually in the bedroom but also the bathtub when I'm taking a bath I take my vibrator into the bath with me and have a little fun while I relax in the bathtub taking a bath. 😃
The shower has been my favorite place to do it since my early teens. However since the internet came along in the 90s my usual place is in front of the computer, watching porn or sometimes doing it in video chat with others.
Almost always in bed. I wait until my wife is not home, or do it when i wake up or go to bed (we sleep in separate bedrooms, after 37 years--she has very little interest in sex any more). I remove all my clothes, get out some great lube, lie flat on my bed (or sit up a bit with pillow up) and spread a towel underneath, and go at it anywhere from 30 minutes to a couple hours...sheer bliss!!
Living room.Late at night when I have the house to myself during my enema, before my shower. I spread everything out, ready to give. I have some very thick diapers I use for this task. I take it and masturbate and when I am empty, I take the diaper off and sometimes, a little poo has found its way into my vagina. If this happens, I some times get turned on fingering myself and have to rub another one out before my shower.
If I am not alone, I like to masturbate in the tub, But when alone,I like to lay naked on the bed,and let the cum fly all over my chest and belly. or , on skype ,with a friend
Usual place is in the shower, a lovely hot and steamy shower. Sometimes whilst sat at my desk at home watching porn.
Almost always in front of my computer watching porn. I like to stimulate myself with my handheld shower - but don't masturbate there.
In bed before I go to sleep, and in bed in the morning before I get up. Also usually before I get in the shower.
I usually masturbate when I come home for lunch, in my recliner with the laptop. I have a good sex life usually twice on the week-ends, I am on the thought of keeping the prostate healthy with frequent use.
I usually masturbate in the shower.But I have tired it in a car, in a bus, at a friends place and in my different teenroom (the different room I had when I was a teenager)
