Honestly, for the times when you are with a partner who likes foreplay, I like one that is also flavored so that if you decide that you want to change what you are doing, (going from hand stimulation to oral), you don't have to deal with the strange taste of the lubricant. It has to be something not too thick & not too thin and definitely not sticky. It also should be non staining & for some should be latex friendly.
There is one that I got from Spencer's that is just a slight bit tart. The name of it is "Sex Tarts" (by Topco sales). I have the raspberry rush. I really like this one because the flavor stays a long time and because it's water based. At first I was disappointed because it seemed too runny, but I've since found that it is just perfect -not too sticky when you are done and & it tastes great even though it is sugar free. If you don't want to taste it, it is still good because the fruity smell is good and the texture works well!
I think this would be just fine for flying solo as well!
