I masturbate a lot in a relationship. Two scenarios -- he's not interested (and I'm there fingering away while he is blissfully snoring on the other side of the bed) or I am traveling with work (and have no other alternative).

Either way, I tend to have the greater sex drive.

I'm in a relationship and I masturbate:

1) a lot - one helluva lot, 2-3 times per day.
2) occassionaly
3) rarely

I masturbate because:

1) my sex drive is stronger/more constant than my partners
2) I simply cannot get enough sex/orgasms
3) I am not completely satisfied with/fulfilled by my sex life

Hmmm ... all of the above, I love sex with me wife (she gives me the best BJ ever) and cannot see myself being truely unfaithful, but I love to masterbate, orgasm read stories and look at beautiful women in various states of undress and sexuall activity. Does this make me bad, hope not.

(this last one doesn't have to be "bad"; it could be because you have certain fantasies that your s/o doesn't fulfill that can be fulfilled through porn/fantasizing/masturbation).

In a relationship I masterbate occasionally, and I do it for none of the reasons you listed. Quite often I simply can't come before my partner has had enough, and we continue on to hand jobs and whatnot. I'm not at all pleased with this - I'd like to come in tandem, as it were, but I'm always taking too long. (Which can get REALLY sore after a couple of hours).

I also find it incredibly erotic to masterbate with my partner with the room very dimly lit. Something about watching her moan and girate really turns me on.

I'm in a relationship and I masturbate (not sure where the dividing line between 'a lot' and 'occasionally' is, but I'll say a lot (probably once every day or two ... sometimes more).

Probably the first ... but sometimes it's just getting stimulated when my wife's not around. Like if I'm perving Pixies in the early morning.

1. I masturbate nearly every day, even though i am in a long term happy relationship, it compliments and is part of my complete sexual experience.

Here a lot of 1 and 2 and maybe a bit of 3 for good measure. Love my fantasy world too... and ebing able to explore beyond normal real life safely. A bit of cyber and phone sex makes it all the more fun too.

I havnt masturbated in months and months and really havnt the desire to. When the sex is great it just doesnt have any joy to do it alone.
