I jerk off or cum daily.
I had a gf who loved watching me jerk off and I enjoyed doing it for her - one the stories here...

Current gf has kinda lost her sex drive, so we only get intimate once every month or so - she still goes to the gym and has a pretty nice body - so that just makes it worse.
On the occasion we do get intimate an normally finish by jerking on her pussy or tits.
She has caught me once or twice having a quiet wank, just ignored me and went about her business.
I have jerked off sitting in bed while she was getting dressed without her knowing.
I want to get to a point I can do it with her knowing and not really reacting one way or the other.
