For me, I just look at it as something different. I'm married, and while we have a monogamish agreement, I don't really have interest in full experiences. I love getting massages, even when they're just therapeutic. If there's a connection going on there, and there's sensual touch (and maybe kissing) and release, it just enhances the experience. Admittedly, I'm surprised with even myself because one of my biggest concerns with any activity outside of a relationship is fear of over-connection, or it taking away from the relationship. I think I've done a good job at compartmentalizing (if that's the correct term to use here) and enjoying the physical and sexual pleasure for what it is. I've fooled around with some friends recently too, but I know who I want to share every intimate aspect with.
That being said, if this (or any other) activity is detracting from your life/experiences in any way, I think it's a great thing to take a break and do what's best/healthiest for you.
