Does anybody masturbate to their ex?

No. I've only had two other serious relationships and I can't stand either of them. I thought I saw one when I was at the movies tonight with my fiance and it just instantly put me in a bad mood. We have some mutual friends and they sometimes add photos on facebook and he has been in some and I'm just saying to myself "Why, how, what the hell were you doing/thinking?". If anything they both turn me off and piss me off to think of, lol. I had one short (8months) relationship and he doesn't bother me, we aren't friends but no hard feelings but, no. No need/reason to.

Occasionally. If I haven't something to focus my attention, like, say, a picture, then my mind tends to wander - which leads to my often taking longer than usual, and thoughts drifting to distinctly un-masturbatory material. Occasionally, my mind drifts to exes. Though it also drifts to funny scenes from comedies, and playing with Dog :| .

Occasionally. More often than not I don't have erotica or porn clips on, so my brain is just left to fill itself up with hot things. The sex I've had with exes includes some hot things. My brain samples, I can't blame it.

Nope, I like to picture my current bf actually. =^.^=
I'd find it a turn off to think about ex boyfriends while I have a bit of playtime.
