Usually in bed reading erotic fiction.
Think you should just do it in front of your man. Its an amazing turn on and you'd be guaranteed seconds!!
In bed, shower, hotel on my own and together sometimes with OH
bed car couch infront of wife we love to whatch each other outdoors in summer
while viewing porn garage got a big comfy chair in there for shaging and playing
In the shower or bath, nice and quiet!
Generally in bed with porn when i'm bored and alone! Sometimes myself and OH masturbate together :) i like that. I have been known to do it at my friends house if we are having a drink and i stay over, OH keeps sending me filthy messages so once my friend falls asleep.. Im straight to the bathroom to relieve what OH has built up in my mind! :)
In the shower at home, at the pc, down at the beach while in the sea.
In the chair, in bed, out in the bush, or in the bath where you can see the cum float lol. Best is in front of a gorgeous woman though, 
Usually in front of the PC in our computer room. OH works days and I work nights, so I've always a few hours free times before he gets home to get "stuck in" lol.
Apart from that, I masturbate in bed when I wake up if alone and ive the day off or in the beath 90% of the time.
i wank nearly everyday, mostly at night with wife watching or when she is sleeping. But i must confess that there has even been on the odd occassion that i have been at work and wanked in the toilet as im thinking about and imaganing about a woman that had caught my attention while on my way to work and made me feel the need to relieve myself! ;) hehe
Quite often in bed beside my wife, sometimes she'll put her hand on me to see if I'm wanking, and if I've moved my hand away, she'll put it back to my "bit"
Lying in bed...reading porn....listening to fast paced music!!
I rarely ever do anymore. It's only usually if we haven't had sex in a few days and I know it's on the cards for that evening, I'll have a quick one in the morning to make sure I'm not over-sensitive that evening!
Usually in bed after a afternoon nap. My oh tends to do it down stairs late at night once I've gone to bed.. Would love to catch him one day 😋
Quickie wanks downstairs in front of the PC looking at pictures or videos most evenings. At weekends I have more time and so a 'slow Sunday morning' is upstairs in bed with my anal toys and some erotic stories.
