I was just chatting to someone about this and thought I'd post it. When I'm locked I find I give a lot more back strokes and massages to my lovely wife. Stroking and massaging all the parts requested for as long as she desires. We can have a more intimate time with sex being securely locked out of the picture. This is probably the main thing she likes about me being locked. I can give strokes and even include her breasts and around her pussy and it doesn't matter how aroused I get. As I wont be getting in. Sometimes she reaches over takes me by the balls gives a squeeze and pulls me to face her and softly demands "Stroke". Not sure if the balls bit is considered sexual. But she keeps a grip of them to make sure I don't touch where she doesn't want. I often think the cage to remove cock from the equation and ball grip to control the stroking etc. For me it feels sexual but for her it's probably more like having a remote control device.
